Tetramethylammonium hydroxide (TMAH or TMAOH) is a quaternary ammonium salt with molecular formula N(CH3)4+ OH−. It is commonly encountered in form of concentrated solutions in water or methanol. TMAH in solid state and its aqueous solutions are all colorless, but may be yellowish if impure. Although TMAH has virtually no odor when pure, samples often have a strong fishy smell due to presence of trimethylamine which is a common impurity. TMAH has several diverse industrial and research applications. (Wikipedia).

Making Calcium Peroxide (CaO2)
In today’s video we are making calcium peroxide from sodium hydroxide, calcium chloride and hydrogen peroxide. Calcium peroxide is an oxidizing agent and it could be used to make oxygen by simply heating it. Our yield was low but we managed to make some. Just to put it somewhere: the produ

Make Hydrobromic Acid Revisited 2018
We show how to make hydrobromic acid. Hydrobromic acid is the bromine analogue of hydrochloric acid. While too expensive to use as much as hydrochloric acid, it's often used when the bromine element itself is needed. For example a major use is the synthesis of organobromine compounds like
