MERCURY(II) SULFATE CAS#231-992-5
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.
White crystals or powder. Mercuric sulphate decomposes on contact with water into yellow insoluble basic sulphate and sulphuric acid. The products of decomposition of mercuric sulphate include oxides of sulphur and oxides of mercury. Mercuric sulphate is incompatible with acetylene, ammonia, and strong acids and corrosive to iron, magnesium, aluminium, zinc, lead, and copper.
Odorless white granules or crystalline powder. Denser than water. MERCURY(II) SULFATE is toxic by inhalation and by ingestion. MERCURY(II) SULFATE is used in medicine, for gold and silver extraction, and to make other mercury compounds.
Decomposed by water to yellow mercuric subsulfate and sulfuric acid, which is corrosive.
