Description and Uses
Mercuric sulfate is a white, odorless, crystalline solid. Molecular weight= 296.65; Freezing/Melting point=(decomposes). Hazard Identification (based on NFPA-704 M Rating System): Health 3, Flammability 0, Reactivity 0. Decomposes in water.
Mercury(II) sulfate is used for gold and silver extraction, and to make other mercury compounds. Used as catalyst in the conversion of acetylene to acetaldehyde and used as a electrolyte in primary battery. It is commonly used as a catalyst in oxymercuration-demercuration, a type of electrophilic addition reaction.
