Product Description
Zinc sulfate heptahydrate powder
Zinc sulfate heptahydrate is a Inorganic Chemicals.Zinc sulphate heptahydrate is white granules or powder at normal temperature and has a molecular weight of 179.47, also known as cesium, zinc technetium, and a density of 1.957 g/cm3. It is easily soluble in water, slightly soluble in ethanol and glycerin, and is gradually weathered in dry air. At 39°C, ZnSO4·7H2O loses one crystal water and turns into ZnSO4·6H2O. At 70°C, it loses the crystallization water and turns into ZnSO4·H2O. At 280°C, it loses all the crystal water and becomes anhydrate. When heated to 767°C, it decomposes into zinc oxide and sulfur trioxide.
