In this video we finish up Chapter 1 and begin to lay bare carbons dirty secrets. This video covers sp3, sp2, and sp hybrid orbitals, their bonding, and their geometry. These are what you will actually be dealing with for the rest of the course so this lesson is vitally important if you wish to exercise god-like power over the elements. Orbital hybridization is seen everywhere in chemistry; even inorganic chem.

I prepare fulminating gold from chloroauric acid and from that I make potassium dicyanoaurate(I) by addition of aqueous sodium potassium cyanide solution. After crystallization of the K[Au(CN)2] (got a good timelapse!) the dicyanoaurate(I) is reacted with concentrated HCl and heated. This precipitates out aurous cyanide AuCN. The Handbook of Preparative Inorganic Chemistry said that moist AuCN was photosensitive to sunlight but that does not appear to extend to the compound under water (at least not in the short term)

In this video I prepare a polyoxometalate of molybdic acid and arsenic acid which precipitates out as the potassium salt. I originally had a lot of trouble with this prep but I finally figured out the trick to it. If you follow the procedure I show in the video you will easily be able to make this brilliant yellow compound.

"How to Text Him" Guide...

The Strange Text That Makes A Man Shake With Obsession?

Keep reading This Letter Here ✅ https://bit.ly/3tGVGHG

Sarah's phone buzzed on her coffee table… and it was from him.

Her hands shook as she picked up her phone to read what he had just sent... and her world flipped upside down.

“I’m breaking up with you,” it read.
She dropped her phone on the table and its screen shattered. Her mind raced with reasons why he would leave her… why he would just give up so easily...

Was it because of the new girl at the office? Have I not treated him right?

Is he sick of me? Am I not pretty enough for him anymore?

No matter how hard she tried she just couldn't fight back her tears... that is…

Until she remembered the magical text message that her friend taught her...
The text message that would change his mind about breaking up with her...

The strange, simple text that would cause his heart to burn with an intoxicating desire every time he thought about her...

Manganese Heptoxide - Mn2O7

By combining sulfuric acid (drain cleaner) and potassium permanganate (filter regenerative substrate), manganese heptoxide is formed.

DO NOT TRY THIS (AT HOME)!

MANGANESE HEPTOXIDE IS TOXIC.
MANGANESE HEPTOXIDE IS EXPLOSIVE.
Mn2O7 GOES OFF WITH A SINGLE DROP OF ORGANIC SOLVENT.
ANY ORGANIC MATERIAL THAT COMES INTO CONTACT WITH Mn2O7 WILL IGNITE, INCLUDING YOU, PAPER, COTTON, THE CARPET, THE DRAPES, ETC.

YOU HAVE BEEN WARNED.

IN CASE OF ACCIDENTAL OR EXCESS Mn2O7 GENERATION:

IMMEDIATELY WASH ANY MANGANESE HEPTOXIDE AND SURROUNDING AREA WITH WATER.
THIS WILL DESTROY THE MANGANESE HEPTOXIDE, AND FORM PERMANGANIC ACID.
DO NOT WASH THIS DOWN THE DRAIN!
NEUTRALIZE WITH SODIUM (BI)CARBONATE.

In this video I prepare selenium tetrachloride from selenium metal and chlorine gas in concentrated HCl, I then use the stock solution of selenium tetrachloride to produce cesium hexachloroselenate and ammonium hexachloroselenate. Both products are very reactive with water and moisture so I stored them under the solutions they were precipitated from.

In this video I finally conquer potassium octacyanomolybdate using a prep from a paper from 1974. In this prep potassium molybdate dihydrate K2MoO4 (made from ammonium molybdate and KOH) is reduced with potassium borohydride and glacial acetic acid in the presence of sodium potassium cyanide (made in the usual way). It still threw me some pretty wicked curve balls like the final product being obtained as an oil that had to air dry; didn't see that one coming. But in the end I obtained a nice, bright yellow product exactly as described in the literature! See? Hard work and perseverance really does pay off!!!

In this video I attempted a prep of telluric acid from tellurium and chloric acid as described in the Handbook of Preparative Inorganic Chemistry page 452. However, I ended up getting TeO2 instead. I'm still calling this a win because this turned out to be a VASTLY superior way of making TeO2 than anything else I have ever tried. And TeO2 is a common precursor for other Te compounds.

In this first of its kind pre-experiment video I lay out the groundwork for how we will be doing the experiment as well as discussing astrology; a topic so intertwined with alchemy that we simply cannot neglect covering it if we wish to create an authentic alchemical product. It doesn't matter if we believe astrology has any bearing on reality. The ancients did. MUCH in alchemy will remain totally mysterious without a solid grounding in classical astrology. I barely even scratch the surface in this video but it is enough for you, dear viewer, to make sense of the experiment when we carry it out. :-)

This prep is fast, high yield, and very easy to carry out as it only takes HgCl2, dry ammonia gas, and anhydrous ethyl acetate.

In this video I prepare the lead analog of ammonium hexachloroplatinate from lead(II) chloride, chlorine gas, and ammonium chloride. The prep turned out to be extremely easy to do and not nearly as difficult as the literature makes it seem like it would be. It would be a good prep for an intermediate level amateur chemist who is comfortable working with chlorine gas and soluble lead salts (both of which can be deadly). Ammonium hexachloroplumbate decomposes in water to PbCl2, Cl2, and NH4Cl but it is soluble without decomposition in 20% HCl,

DANGEROUS!

In chemistry you are told never to mix Sulfuric acid Potassium permanganate.

If you mix concentrated Sulfuric acid and Potassium Permanganate it creates the highly unstable manganese(VII) oxide (Mn2O7) which reacts violently with organic compounds and this can be shown through its action on cotton wool soaked in ethanol.

In this example the ethanol has been saturated with Boric Acid, so that once the ethanol has burned away the flame changes to green for a little bit of extra flare.

This little demo lets you show the dangers without risking life and limb.

Safety point!

Mn2O7 is corrosive, explosive and oxidising. Wear a face shield or goggles.

We love beryllium!

Here, we show you how to prepare an important starting material for the preparation of organoberyllium compounds. Please check our publication for more details and other interesting compounds:
DOI: 10.1002/asia.201801800

However: DO NOT REPEAT THIS AT HOME! BERYLLIUM COMPOUNDS ARE VERY TOXIC AND ONLY EXPERIENCED CHEMISTS SHOULD HANDLE THEM! ONLY DO THIS IN A FULLY VETTED LABORATORY.

Please use:
- disposable gloves
- lab coat
- safety glasses
- face mask with particulate and chemical vapour filters
- a well-ventilated fume cupboard
- an N2 or argon dry glove box
- extreme vigilance

Make sure to:
- clean all surfaces regularly
- clean your glassware separately from your lab mates
- dispose of all beryllium contaminated waste and chemicals separately and according to your country's regulations

A good introduction into beryllium chemistry:
DOI: 10.1002/anie.201601809
DOI: 10.1002/ange.201601809

Disclaimer: The chemistry you see here was performed in Australia. I am very grateful to my mentor Prof. Cameron Jones. I am also grateful for the video and audio by Steven Morton. This is a pilot project. More condensed and professional videos shall follow.

Thanks for watching!

In this video I attempt to prepare the closest indium analog of rubidium hexabromothallate(III) Rb3[TlBr6] that the literature says can exist, namely rubidium pentabromoindate(III) Rb2[InBr5]. I had nothing more to go on that two mentions of this compound in various lists of indium complexes and double salts. It took 3 tries but I did get rubidium pentabromoindate so far as I know along with at least one other cool indium compound.

This is not really a gas mask. But it is a way to get fresh air to your lungs in a room that is filled with noxious gases. No filters or canisters needed and nothing needs replaced after each use...….like filters or carbon etc. IF YOU WANT TO BUILD A REAL GAS MASK WITH CARTRIDGES THEN WATCH THIS https://www.youtube.com/watch?v=Scn90dHA3Fk&feature=youtu.be
..AND REMEMBER unless you are exhaling then your tongue should be covering the exhale tube. This is because that tube will have a lot of CO2 in it from you exhaling into it. And you do not want it to get in to the mask part where the fresh air comes from. So this is a constant repetition of covering the tube with your tongue when you inhale and moving your tongue away from the tube when you exhale.

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! :-)
