In chemistry, disulfate or pyrosulfate is the anion with the molecular formula S2O2−7. Disulfate is the IUPAC name. It has a dichromate-like structure and can be visualised as two corner-sharing SO4 tetrahedra, with a bridging oxygen atom. In this anion, sulfur has an oxidation state of +6. Disulfate is the conjugate base of the hydrogen disulfate (hydrogen pyrosulfate) ion HS2O−7, which in turn is the conjugate base of disulfuric acid (pyrosulfuric acid). (Wikipedia).
Make p-chlorobenzyl chloride (from para-chlorotoluene) 3rd step in making pyrimethamine

Hexamine is a solid fuel with a high energy density, and we make a salt with it using perchloric acid, a very good pyrotechnic oxidiser. I also try to be funny at the end. At the time, I remember it being actually funny to me, but now it's really quite hard to watch. Oh well, progress I g

Make Sodium Magnesium Oxide Aggregate - A Substitute for Sodium Metal
In this video we make sodium magnesium oxide aggregate. A useful substitute for sodium metal in most cases. Doing this is very simple, we combine 30g of magnesium metal turnings or powder and 40g of sodium hydroxide in a metal container. The mixture is ignited with sparklers or a fuse and
