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
In this video I demonstrate the synthesis of antimony(III) iodide from ground antimony metal and iodine in toluene. The protocol for this synthesis was taken from the Handbook of Preparative Inorganic Chemistry, 2nd Edition, Volume 1, page 614. You can find more information about this compound and its chemistry on atomistry.com at the link below. SbI3 reacts with water to produce antimony oxyiodide. This can be difficult to clean off glassware but it will dissolve in strong HCl quite readily.
Errata: At 14:30 the subtitle should read "Her condition degraded over months until by the end she appeared to be in agony although her docs said they didn't think she could even feel pain anymore."

In this video I demonstrate the extraction and isolation of harmala alkaloids from Peganum harmala seed powder. The method used is taken from a paper in the American Journal of Undergraduate Research titled Extraction, Identification, and Quantification of Harmala Alkaloids in Three Species of Passiflora. The alkaloids are tracked through out the extraction by their fluorescence under UV light.
In this video I synthesize o-aminobenzoic acid (anthranilic acid) by oxidation of phthalimide with sodium hypochlorite solution. The protocol I used came from prepchem.com although I modified it based on suggestions given by ChemPlayer on their BitChute video where they carry out the same reaction but using a different synthesis protocol. I try to do all my own work but after attempting this synthesis once and having it crash and burn I decided to consult the masters of home chemistry. There is no shame in accepting help from the great chemists who have come before us.
The prepchem protocol had an additional feature that I didn't see anywhere else where anthranilic acid that would have been lost in the filtrate was recovered as cupric anthranilate which is then reacted with H2S gas to produce copper(II) sulfide and free anthranilic acid in solution. Although I did not do the reaction with the hydrogen sulfide gas I did recover the anthranilic acid from the filtrate as cupric anthranilate in order to calculate a yield for the synthesis. That cupric anthranilate can be stored for conversion to free anthranilic acid later or it can be used as is in other experiments.

This is my first time experimenting with putting chemistry to music. It's crude but I'm learning. In this clip I demonstrate the formation of iodine monochloride vapors, liquid iodine monochloride, and iodine trichloride (both crystalline and amorphous). The clip concludes with breaking down the reaction products with water. Hydrolysis produces iodic acid, hydriodic acid, and hydrochloric acid.
PS It is possible that some of the color in the final solution is coming from dissolved iodine trichloride. If the pH is very low (the final solutions pH is around 2) and the chloride ion concentration is very high (this I am less sure of) then iodic acid can be reduced to iodine trichloride. This should only be stable in a concentrated HCl solution however it is possible that the final solutions composition met those requirements. The final solution seems to be a bit too orange to be composed of just iodine and iodine itself is not very soluble in water. The fact that NO solid iodine remains and a clear solution was produced by hydrolysis makes me wonder if some ICl3 formed in the final acid solution.
These are a few short clips of some "experiments" I did with nitrogen trichloride about a year and a half ago. Honestly I was just having fun. Obviously this kind of thing is EXTREMELY dangerous. You will note that I built a special enclosed pit (the bunker) to do these "experiments". Nitrogen trichloride is so unstable that sometimes it explodes for no particular reason at all (as you can see in one of the clips). I am not going to include the method for producing this chemical in this video although we may visit that topic in a future video as NCl3 does have some use in organic synthesis as an oxidizer (as a dilute solution in chloroform).
Even though I don't tell you how to make NCl3 (it's coming soon!) we all know how things are these days so I am still going to include an obligatory: DON'T TRY THIS AT HOME! ;-)
I made this video as a refutation to a few points that Robot Head (one of the finest channels on YT) brought up in his video about that Bob Lazar movie. I love Robot Heads channel and his videos are so well done and funny they are in a class unto themselves. THIS IS NOT AN ATTACK AND NO DISRESPECT IS INTENDED!
RH furthered the myth that uranium and other radioactive elements are not available to the general public but in fact nothing could be further from the truth. And you don't need permission, permits, or any of that nonsense. You just need a bank card and about $50 per sample. I will show you why that isn't a problem in the video as well as explain some of the basics about radiation.
RH also made some statements about thallium saying it was "banned" in the US when in reality it's only banned in consumer products. It's readily available in any quantity you wish. However, I am not going to address that in this video because I think that was covered in my thallium(I) sulfate video. As I said there ANYONE can turn thallium into a colorless, odorless, tasteless poison. I simply bring it up for the sake of completeness.
Cesium Tetraiodothallate or Cs[TlI4] is a strongly colored double salt complex with a moderate solubility in water. Its formation was used as a test for the presence of thallium(III) ions in a sample back in the days before modern instrumental analysis. I prepare this double salt and then evaporate the liquid to get extremely tiny crystals of Cs[TlI4]. I then use an electronic dissecting scope to view the crystals at 1600x magnification. www.poormanschemist.com
Taking inspiration from my fellow YouTube chemists I thought that I would do a short video tour of my lab. I've taken a lot of inspiration from the YouTube chemistry community over the years. Although I already had a lab of sorts before I discovered the YouTube chemists it's nothing like the one I have today. After watching many of those videos I thought "If they can do it then why can't I?" The obvious answer to that question is: it's really expensive! But is it? Not only have chemicals and equipment become much more available over the last several years the prices on them have dramatically dropped. These days we live in a kind of golden age of home chemistry where anyone with enough single minded determination can have their own respectable chemistry lab. It is my sincere hope that this video will inspire others out there to take the bold step of making their personal chemistry lab dreams a reality.
Zirconium, as it turns out, is the horror movie monster of the periodic table that just keeps on coming no matter what you throw at it. Every time I kicked it up a notch it just smiled and kept on coming. Although I finally managed to make some headway it was far from anything that could be qualified as a success. I thought that some of you might find it amusing to watch me get owned by some P.O.S. transition metal. :-)
I replicate Nile Red's synthesis of elemental bromine from aqueous alkali bromide, 16% HCl, and trichloroisocyanuric acid a.k.a. trichloro-s-triazinetrione obtained from 3" pool chlorinating tablets. You can see his video that I took the synthesis protocol from by clicking the link at the bottom of the description. A typical run of this synthesis requires the materials listed below. Since I did my run from bromide that I had recovered and recycled from previous reactions my measurements were different. You can find the step by step protocol for this synthesis on my website at: http://www.poormanschemist.com/PMC_Grimoire/PMC_Grimoire.html#bromine
Sugars are complex. There are entire areas of chemistry that focus on this. They are essential to many biological functions. The most obvious of which is as a source of energy from food.
You might know of sucrose as table sugar, fructose as fruit sugar and a few others. These names are a sample of the wider possible options. The many other options get tricky as the get longer, more complicated and varied.
There are trioses, pyranoses, furanoses and more that just tell you how many carbons are in the ring at the core of the molecule. Than there are other features like the side a particular part of the compounds is on. Than other possible ways to name a sugar come into play.
That is what this video is trying to split into smaller more easily understood parts. What is it that gives a sugar a particular name.
This is important as naming schemes have come and gone. These have left behind names that are similar to others but different in nature. This can create some confusion if you get used to this system and than encounter something that deviates.
Just showing how to figure out formal charges on atoms in a molecule or ion. I am to busy to do any experiments right now so I thought I would do this video so people know I am not done doing videos and I am still alive
We prepare a strong solution of aqueous ammonia from the reaction of ammonium chloride together with sodium hydroxide, show what happens as the ammonia gas dissolves in water, then do a few fun tests with the product.
Following from an earlier video that presented evidence of the origin of life. This brief video shows new experimental evidence of how these mechanisms might work in creating simple cells and similar biological apparatus.
The researchers disturbed the equilibrium of a closed environment and watched as the contents underwent a change from a random array to a crystal lattice.
*NOTE* The video shows primarily important definitions but does not show how to balance equations. Also I made this for fun as I am in grade 10 (as of the time this video was uploaded) *MUSIC* https://m.youtube.com/watch?v=lqPhHMwqzsY
In the illustrious words of Vinny Boberino..........UP YOUR NOSE WITH A RUBBER HOSE,,,,,,,,It is going to take a while to finish my cellulose nitrate ester video so in the mean time i got a couple easy videos like this one. I only go over the 2 main types of hoses used by home chemist although i am sure there are more types. And then i show my soxhlet apparatus in the "extra video" part at the end
ATTN: THERE IS A MISTAKE IN THE STOICHIOMETRY IN THE EQUATION AT THE END OF THE VIDEO.....IT IS Cl2 +2NaOH >>>> NaClO + NaCl + H2O and not Cl2 + 4NaOH >>>> 2NaClO + 2NaCl +2H2O............Same with iodine...........it should be I2 + 2NaOH >>>> NaIO + NaI + H2O..................... OXYACID NOMENCLATURE............Just some misc stuff showing some patterns in oxyacid nomenclature and etc...
Just another "HOW TO GET" video. Pretty pure stuff but definitely needs a slow recrystallization from water to clean it up good.....THIS IS ALSO A GOOD SOURCE FOR ANHYDROUS AMMONIA GAS NH3 OR ammonium cation

When I was four, or five, years old one summer I got the idea into my head that I could use a chemistry set to make a solution that would make bees docile and they would crawl around on your arm and not fly away. We did this in my back yard and we did not get stung once.
In the video I claimed that this was before kindergarten when I was four years old, but it might have been the summer after kindergarten when I was five years old. I remember it as when I was four, but that seems very young to me now....

We prepare Urushibara type-A nickel starting with basic nickel carbonate, preparing a nickel chloride solution, reacting with zinc powder, and then dissolving excess metal away using acid before washing the product.
We complete the steps in the sequence from para-nitrobenzoic acid to create the local anaesthetic drug Benzocaine, firstly by esterifying the acid and then by reducing it using freshly prepared sodium dithionite.
As we learned more about chemistry we discovered that it is really the study of how electrons work; learning this can give you a much deeper understanding and appreciation for the subject, so here's our quick tutorial on the basics.
After an interesting finding that phosphorus pentoxide can catalyse Friedel-Crafts reactions without an acyl chloride being needed, we undertook some experiments to find out if this was because it could perhaps generate acid anhydrides.
We perform in interesting experiment to see if a Friedel-Crafts reaction can be performed without the use of an acyl chloride. We utilise benzene and propionic acid, and aluminium chloride as a catalyst, and then add phosphorus pentoxide in an attempt to drive the reaction.
We prepare potassium thiocyanate from potassium ferrocyanide via a molten reaction with elemental sulfur and sodium carbonate. We extract and crystallise a pure solid product from the reaction mixture.
We perform the classic preparation of concentrated ('fuming') nitric acid via reaction of a nitrate salt and sulfuric acid. We then react this with phosphorus pentoxide in order to see if we can catch the never-seen-before-on-TV nitrogen pentoxide.
We originally filmed this reaction on the eve of the feast of Saint Barbara, performing the condensation of urea and diethylmalonate to produce barbituric acid, the parent molecule for barbiturate drugs.
