Molecular formula: NiSO4 · 6H2O molecular weight: 262.85

There are three kinds of nickel sulfate: hexahydrate, heptahydrate and anhydrous. The industrial products are the mixture of the first two, and the appearance is emerald green granular crystal. Soluble in water, the aqueous solution is acidic. It is easily deliquescent and slightly weathered. When heated to 280 ℃, all crystal water is lost and yellow green.
