In this video I synthesize sodium metavanadate and I then use that to synthesize the sodium, potassium, and ammonium salts of the vanadate polyoxometalate compound described in The Handbook of Preparative Inorganic Chemistry, 24-Vanadic Acid-2-Phosphate.
Note: There is a missing title card at 23:23. It should read "The Ammonium Salt" but instead shows a black screen with no text. My bad! Don't skip those as those were the best of all!

DO NOT TRY THIS AT HOME! After doing something so cerebral I thought I would do something fun and so I put together a video of what happened when I dumped out molten potassium nitrate I was using to clean carbon out of my crucibles onto a pile of dried leaves. The result was unexpected.

I am rolling out a new series in which various neuropharmaceuticals are discussed from an organic and biochemistry perspective. These are not "how to" videos but rather an academic examination of these compounds. Their chemistry, the synthetic routes by which they are produced in nature, industry, and the laboratory, and their applications in medicine will be discussed.

In this first video of the series we take a look at the chemistry of tryptamine and the N-mono and N,N-disubstituted tryptamines. In the next video we will discuss the more exotic substituted tryptamines, lysergic acid and its amides, and we will conclude the discussion on tryptamine chemistry with ibogaine.

In this short video I demonstrate the reaction of clove oil, pseudoephedrine tablets, and sassafras oil with a saturated solution of picric acid in water as well as the oxidation of silver with bismuth tetroxide to what I highly suspect is silver(I,III) oxide.

In this short video I show the synthesis of chloroauric acid, nanoparticles of gold in suspension also known as Purple of Cassius (produced accidentally but I still caught it on film), auric bromide Au2Br6, aurous bromide AuBr, and recycling gold from solution by the precipitation of metallic gold using sodium metabisulfite.

In this video I do a practice run of the synthesis of sodium dithionite that I found at the website linked below. This was just to get a feel for how the procedure goes, what things I need to research further, and how the product behaves. I need sodium dithionite do try (and probably fail at) the synthesis of uranium(IV) oxalate. Not only is it supposed to have a nice deep green color but it also gives me something to do with the 3 grams of uranyl acetate dihydrate I have since the protocol I will be working from starts with that salt in particular.

In this video I make eight different compounds starting with hexachloroplatinic acid that was freed from residual HNO3 and HCl that remained from dissolving the platinum in aqua regia. Starting from this I make several hexachloroplatinates, platinum tetraiodide, platinum sponge/platinum black, platinum disulfide, dipotassium hexathiocyanatoplatinum(VI), and platinum triselenide. Crystal films were created and photographed using the dissection scope as usual and the photos are included after the end of the video.

In this short video I demonstrate the synthesis of dibismuth tetroxide from potassium bismuthate that I prepared previously. You can find the synthesis of potassium bismuthate and of dibismuth tetroxide on pages 628-629 of the Handbook of Preparative Inorganic Chemistry. You can download a PDF of this book at the Zlibrary. A link to the ZLibrary homepage as well as a direct link to the download page of the textbook can be found below.

In this double feature I do the synthesis of crystalline sodium phosphotungstate and a solution of sodium silicomolybdate suitable for the selective precipitation of rubidium and cesium ions but not sodium or potassium ions. Since both syntheses are pretty simple I decided to combine them in my first ever double feature video I hope that y'all enjoy it!

In this video I attempt the synthesis of chromium(III) glycinate. Things did not go as planned. While purple basic chromium(III) glycinate was produced and largely isolated relatively easily the elusive red crystals of chromium(III) glycinate were not so easily obtained. In the end I did get them but not in a way I expected.

In this final video in the series we examine crystal films and clusters of rare earth salts. Scandium, yttrium, and several lanthanides are presented for your enjoyment. I also tried using different lighting techniques to bring out as much of the 3-D structure of the crystals as possible. In my opinion this is the best one yet since these crystals looked like nothing I've ever seen before.

In this video I show off some more photos of crystals films and tiny crystal clusters grown from large droplets of aqueous or acid solutions of the salts. My crystal growing technique continues to improve. Some of these crystals were grown by evaporating the droplet slowly in the desiccator using only the sun as a heat source. Others were grown over desiccant in a vacuum desiccator. Even those not grown under vacuum usually spent some time in there to remove the last traces of water before being photographed. And the thorium nitrate crystals were grown by allowing a large droplet of the solution evaporate over low heat. All of these methods produced fantastic crystals; much better than last time in my opinion.

PS On Nov 20th, 2019 I discovered that this video had been deleted on YT. They did not send me an email or notify me in any way. I just logged in one morning and it was gone. I presume they did this because of the music used in the video. I'm not really too upset about them taking down the video (I think it's pretty fucking ridiculous though since people filming themselves playing US2 make videos with this exact same music) but I AM upset that I wasn't notified about it. So I am going to follow Styxhexenhammer666's example and make this a BitChute exclusive. More will be coming.

In this video I react pellets of molybdenum metal with molten potassium nitrate in order to create molybdenum trioxide for a future experiment (going to try to make some sodium silicomolybdate which is used to selectively precipitate rubidium and cesium ions). I only filmed the reaction and not the work up of the MoO3 because honestly I am still not 100% sure how I am going to do it. But the reaction looked cool as hell so I thought I would share. At the end of the video there is an update on the identity of the mystery praseodymium compound I made by reacting Pr(III)(OH)3 with 35%H2O2.

This short video is composed of pictures of crystal films and crusts that I have grown from large droplets of aqueous or acid solutions of various inorganic salts. The droplets are poured out onto a watch glass and heated for a time using a heat gun. Once the droplet is hot the watch glass is placed into a vacuum desiccator over 3A molecular sieves or solid NaOH depending on the compound involved. Once the droplet is dried the resulting crystal film or crust is photographed at 1600x magnification using a digital dissection scope.

In this approximately 100 subscriber special video I spend a few minutes telling you a little bit about myself followed by the synthesis of rubidium dichromate from ammonium dichromate and rubidium chloride. This synthesis can also be carried out using cesium chloride instead of rubidium chloride to obtain cesium dichromate. You could even mix it up by reacting one mole of ammonium dichromate with one mole rubidium chloride and one mole cesium chloride to obtain cesium rubidium dichromate. However, you totally shouldn't because obviously you shouldn't repeat anything that you see here. You could get hurt or become educated or other dangerous things. :-)

In this video I replicate an experiment I did about a year ago where I react Pr(OH)3 with 35%H2O2 to obtain a yellow solid of unknown composition. If anyone has any ideas I would love to hear them! Enjoy!

In this video I demonstrate a lead dioxide based thermite so that people can see this apparently legendary thermite reaction. Here at the Poor Mans Chemist we strive to give the public what it wants. I was hoping for something a bit more explosive but this run of the mill thermite reaction is all I got. There were no casualties.

In this video I attempt to create indium(I) iodide first by refluxing indium(III) iodide dissolved in xylenes with indium metal and then by direct union of the elements under a dry carbon dioxide atmosphere. While I achieved a better looking product out of the direct union of the elements I believe that the method of refluxing InI3 with In in xylenes has great potential. If my indium(III) iodide had been of better quality and if my indium were powdered I am certain I would have had a much higher yield. The method for direct union of the elements came from the atomistry.com article on indium monoiodide whereas the idea for refluxing InI3 with In in xylenes came from Wikipedia. These were the only "instructions" I used in making this compound. I also referenced the atomistry.com article for indium(III) iodide. Links to all are below:

This is what happens when you don't close up your bottles of chemicals promptly. In this short clip I demonstrate the process of deliquescence in which a solid compound absorbs enough water from the atmosphere to completely dissolve itself in that water. It was a rainy day when this was filmed and the air quality meter gave a reading of 99% relative humidity so this is a bit of "worst case scenario" but this happens with compounds like sodium hydroxide even on dry days indoors. So make sure you keep your chemicals bottles closed tightly when you aren't using them or else your expensive chemicals might turn into unusable solutions.

I am making this so that i can prepare some indium triiodide for an upcoming video where I try out some shit I read on Wikipedia and react it with metallic indium in refluxing toluene to prepare indium monoiodide. Why? Because it's a deep red-purple compound in an unusual valence state! So colorful weird shit! That's all the reason we need on this channel! :-)

In this video I demonstrate the conversion of diethylamine hydrochloride to the free amine by reacting it with 40% sodium hydroxide. The mixture was distilled although that wasn't really necessary to get most of the product. The method I used came from the end of the diethylamine synthesis protocol on prepchem.com and can be found at:

DO NOT TRY THIS AT HOME! In this video I demonstrate a very fast burning thermite mixture boosted by an additional oxidizer. Pyro grade aluminum powder, manganese dioxide powder, and potassium perchlorate powder are combined in the usual way. Then the mixture is ignited using a potassium permanganate-glycerol mixture which provided a delay that allowed me to move to a safe distance.

A thermite reaction, more properly a Goldschmidt Reaction or the Goldschmidt Process, is the reaction between a powdered metal (usually aluminum) and a metal oxide. The reaction is driven by the high stability of the aluminum oxide product versus the metal oxide reactant. Initially heat must be injected into the system to melt the aluminum which frees it of its passivating oxide coating and allows the highly reactive aluminum metal to come into contact with the metal oxide. And then away we go!

This short clip is one of the videos I'm most proud of. I've been trying to improve my editing skills so that I can give y'all better videos and this is the result of my latest practice session. I decided to go ahead and recrystallize the anthranilic acid I got from the clip where I displaced it from copper anthranilate using H2S. I am going to make a video in the near future where I make anthranilic acid again but this time I am going to use Br2 in NaOH (so hypobromite) with clean HCl. None of this hardware store shit. This is a nut that I am going to crack come hell or high water. :-)

In this video I attempt (and largely succeed) to produce the infamous Scheele's Green and Paris Green pigments responsible for so much death and suffering for over 100 years from the late 1700s to the late 1800s. I synthesize both from elemental arsenic that I dissolve in HNO3 and H2O2 to produce arsenic acid as well as from arsenic trioxide produced by thermal decomposition of a mixture of arsenic trioxide and arsenic pentoxide I made previously (don't miss the accident that happened on THAT one!). I also discuss some of the history of arsenic in the classical world including the well-known arsenic based "inheritance powders". There is also some bonus footage of copper acetate crystals under high magnification (stills this time, no super shaky video) after the end of the video.

In this short video I demonstrate a spot test for tellurate scaled up to be done in a test tube. Some runs were better than others but I was able to get some beautiful shots of convection and crystallization happening at the same time. Although I do not know the exact identity of the compound produced I believe that it is some variant on potassium copper(III) tellurate. A copper(III) compound is weird enough to warrant a short video all it's own.

Errata: At 1:36 there is an error in the chemical equation presented. It should read as follows:
(NH4)2S2O8 + 2NaOH -- Na2S2O8 + 2H2O + 2NH3

Ever since I was a boy I have dreamed of building my own chemistry lab. I wanted it to be a kind of self-assembled chemistry set put together piece by piece by a professional chemist so it wouldn't be lame. Eventually I grew up and became my own professional chemist and after years of hard work and sacrifice the dream has finally become a reality. Join me as I investigate some of the more interesting aspects of the central science of chemistry including organic synthesis, inorganic synthesis, reagent synthesis and use, instrument-free analytical techniques and procedures, and much more.
