Cupric sulphate

Cupric Sulphate (also known as Copper(II) Sulphate) is a chemical compound with the formula CuSO4. This salt exists as a series of compounds that differ in their degree of hydration. The anhydrous form is a pale green or gray-white powder, whereas the pentahydrate (CuSO4·5H2O), the most commonly encountered salt, is bright blue.

History

Cupric Sulphate has been used for centuries and was known to the Romans as Cuprum or Copper, from where it gets its modern name. The process of its creation was later refined by the alchemists and then by modern chemists.

Production

Cupric Sulphate is produced industrially by treating copper metal with hot concentrated sulfuric acid or its oxides with dilute sulfuric acid. For laboratory use, cupric sulphate is usually purchased.

Uses

Cupric Sulphate is used widely in agriculture, primarily as a fungicide. However, it can also be used in the preparation of other copper compounds, in dyeing and calico printing, and in electroplating baths. In the field of medicine, it is used as an emetic.

Safety

Cupric Sulphate is harmful if swallowed and can cause burns and eye damage. Therefore, it should be handled with care.
