Copper Sulphate

Copper Sulfate

Copper Sulfate

Name: Copper sulphate
Synonyms: Copper (II) sulfate anhydrous; cupric sulfate anhydrous; copper sulfate anhydrous green powder; copper sulphate; copper(2+) sulfate hydrate (1:1:5); copper sulfate; copper(2+) sulfate; copper(II)sulfate
Formula: CuSO4
Molecular weight: 159.6097
CAS No: 7758-98-7; 10124-44-4
Properties: Blue crystalline solid. Copper sulfate decomposes before melting and loses four water molecules at 110 ℃ and all five at 150 ℃. At 650 ℃, copper sulfate decomposes into copper oxide (CuO) and sulfur trioxide (SO3). When heated in an open flame the crystals are dehydrated and turn grayish-white.Copper sulphate anhydrous (CuSO4) form is a pale green or gray-white powder, whereas the copper sulphate pentahydrate (CuSO4·5H2O), the most commonly encountered salt, is bright blue.
