In this video I wanted to share some of the things that I learned studying the history of chemistry and laboratory alchemy as a practical science. The alchemical theory of matter is what pre-dated the atomic theory of matter and if you don't know that matter is made of atoms the alchemical theory of matter does have a logic to it. I do not claim to be an expert on the subject merely someone who has studied practical laboratory alchemy for a few years and who can look at it from the perspective of a modern chemist.

People in the past are just as smart as they are today it's simply that their theories were not as advanced as ours. As such they don't deserve the reputation they have among modern scientific circles as a bunch of charlatans and fools. I wanted to briefly explore this fascinating aspect of chemistry's history and show how even today a study of their methods is not unwarranted. ;-)

Diclaimer: I am not advocating for any kind of spiritual view in this video. I personally think that the material universe is all there is and I don't believe in a god or gods, spirits, demons, ghosts, magic powers, psychic powers, or any of that occult rubbish. Nothing against you, dear reader, if you do but I looked for these things for 27 years of my life and I did not find them. Either I am extraordinarily inept or they simply aren't there. But you do you my friend and more power to you! :-)

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 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 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.

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.

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.

The following are briefly described in the video:

01:34 Simple and complex sugars

02:22 aldehyde

02:36 ketone

02:51 alpha and beta

04:13 L and D sugar

06:21 Triose, furanose, pyranose

06:55 deoxy-ribose

07:40 amino sugar and glycosyl amines
