Description of Zinc Sulphate:

Physical and chemical properties: colorless orthorhombic prismatic crystals. Relative density 1.957. Melting point 1000C. Soluble in water (96.5g/100ml water at 200C; 663.6g/100ml at 1000C). Slightly soluble in alcohol and glycerin. Gradually weathers in dry air. It loses all crystal water at 2800C and becomes anhydrous, and decomposes above 5000C.
