In this video, I will explain how mercury can be obtained via a wet-chemical method from cinnabar, thereby avoiding handling mercury vapour. The credit for this process goes to Plante1999 of the Sciencemadness forum.

The chemistry:

First, the sulphur dissolves in sodium hydroxide to form polysulphides and sodium sulphite:
6NaOH + 7S = 2Na2S3 + Na2SO3 + 3H2O
The equation is for the trisulphide (which I calculated for) because I figured that since the sulphur is acting as a complexing agent, more of it would help move the reaction forward.
Na2S3 + HgS = Na2HgS4
Then the mercury sulphide is added, which forms the thiomercurate which appears to have an unfixed formula and therefore requires a fairly arbitrary quantity of sulphur.

The reaction of aluminium and sodium hydroxide is well known:
2NaOH + 2Al + 6H2O = 2NaAl(OH)4 + 3H2
and the hydrogen produced reduces the mercuric ions to mercury:
Na2HgS4 + H2 + 2NaOH = Na2S3 + Na2S + Hg + 2H2O

Combining the equations for ease of calculation of quantities:
6NaOH + 7S + 2HgS = 2Na2HgS4 + Na2SO3 + 3H2O
8NaOH + 2Al + 3Na2HgS4 = 2NaAl(OH)4 + 3Na2S3 + 3Na2S + 3Hg
34NaOH + 9S + 6HgS + 4Al = 3Na2SO3 + 9H2O + 4NaAl(OH)4 + 12Na2S + 6Hg

In the third instalment of my series detailing the processing of household material to obtain samples of the elements, I show how to extract yttrium from fluorescent light-bulbs.

In the second instalment of Elemental Syntheses, I will detail a purification method I created for refining impure gallium metal. In this video I will also display my balance scales. I will also show some of the properties of this element, along with a conundrum I would like your help solving!

The next Elemental Syntheses video in the series will cover chlorine. Apologies for the delay since the last instalment, I've been busy with uni work. I cover a few ways of generating the gas, and contrast its behaviour and properties with air.

In this video, I will show a few ways of preparing pure copper, and a lab-scale version of electrorefining. I will also prepare a sample of potassium cuprate(III), a blue solid in which copper is in the +3 oxidation state.

In the first of my new series I have entitled Elemental Syntheses, I will demonstrate how to synthesise manganese metal starting from the impure manganese dioxide I obtained in a previous video. I will also show some of the properties of this element.

In order to isolate manganese metal, I used a thermite reaction. I have heard of several people having very little success with this method due to the temperatures attained in a typical thermite (they are usually high enough to vaporise manganese. However, I used a small reaction mass, sitting on cold sand on what happened to be a windy day. As a result, a lot of the heat generated was lost to the surroundings, which meant that the metal did not boil away. I didn't put this in the video because I did not have sufficient footage to fit all the information in. I also only thought of much of this after I uploaded this video.

A video on purifying this element from the fungicide, estimating the purity of a sample of sulphur, and a little bit on its allotropes.

Formation of polysulphides:
6NaOH + 7S = 2Na2S3 + Na2SO3 + 3H2O

Oxidation of polysulphides:
Na2S3 + 8H2O2 = Na2SO4 + 8H2O + 2SO2
2NaOH + SO2 = Na2SO3 + H2O
Na2SO3 + H2O2 = Na2SO4 + H2O

Another in the series of preparation of the elements, this one demonstrating two alternative but equally viable methods.

In this video, I will describe several methods of preparing oxygen from household materials, other methods are also possible from less readily available materials. I chose the ones I did to fit with my criteria for this series.

This video does what it says on the tin

In this video, I will prepare some crystalline boron from borax via boric acid, and also attempt to make some boranes (boron hydrides) to demonstrate their pyrophoricity.

This is a response video to a video posted by Aussie Chemist about dissolving a diamond in Piranha solution. I wondered if graphite and charcoal would be any different.

In this video I attempt to prepare an aero-gel precursor from silicon sulphide prepared here: www.bitchute.com/video/Hj3enBXbhBgU/

This video shows the violent reaction between turpentine and crystalline iodine. Turpentine is primarily pinene, and this is the constituent which reacts. Turpentine is made commercially by distilling the resin of resinous trees, usually pine trees, hence the name of its major constituent.

A chemistry classic, a layer of sulphuric acid is put in a test tube, and some ethanol is floated on top. Potassium permanganate is added, and a fiery display results.

In this video, I detail the preparation of amorphous silicon from sand with thermite. This forms as a black powder, because it is not crystalline. It could be made so by melting it under an electric arc, but I do not have the equipment to do this.

A video on hydrates, and the preparation of an unusual hydrate. This procedure was found in a serendipitous discovery during a first year undergraduate practical by a good friend of mine over on the Sciencemadness forum.

This video details an alternative test for the halide ions using silver nitrate, the alternative being to use concentrated sulphuric acid:

In this video I will finally do something with the silicon I prepared in previous videos. I will detail my various attempts and success in preparing it.

Another pretty cool experiment in which a bead of mercury is made to beat like a heart.

In this video, the violent reaction between concentrated nitric acid and sodium thiosulphate is shown.

This video details the preparation of manganese heptoxide, and demonstrates its oxidizing power. I shall use this substance in a later video.

This is a highly dangerous experiment showing the reaction between the first two alkali metals and an incredibly powerful oxidising agent. The quantities I use here are 'safe', but I cannot restrict you from copying in much larger quantities. I do not, however, take any responsibility for this.

Many people have seen the addition of lithium and sodium to water. This video goes further by adding these alkali metals to dilute sulphuric acid (4M) and to concentrated sulphuric acid (98%).

Various chemistry experiments done at home, which is an incredibly fun past time for me. I try to come up with interesting experiments that will are interesting and/or really fun for a variety of reasons. If you would like me to produce a particular video, please suggest it and I will see if I can do it!
At the moment I am slowly working my way through the 92 naturally occurring elements attempting to make each one starting from a household material.
