Rincian Produk

Anhydrous cobalt(II) sulfate forms purple orthorhombic crystals, with a density of 3.71 g/cm³ and a melting point above 700°C. The monohydrate variant appears as crimson crystals, with a density of 3.08 g/cm³ and gradual solubility in boiling water. The heptahydrate form consists of crimson monoclinic prismatic crystals, with a density of 2.03 g/cm³; it dehydrates to the hexahydrate at 41°C, and further converts to the monohydrate at 74°C. Both the anhydrous and heptahydrate forms are readily soluble in water.
