1. Fusion of silicon oxide with potassium hydroxide, 900 – 1000 ° C.
SiO2 + 2KOH = K2SiO3 + H2O.
2. Destruction of potassium methyl salicylate with hydrochloric acid.
K2SiO3 + 2HCl = 2KCl + SiO2 + H2O.
3. The reaction of exchange of potassium chloride and copper sulfide with the formation of the corresponding salts.
2KCl + CuS = K2S + CuCl2.
