Copper(II) sulfate facts

Anhydrous copper(II) sulfate is a white or grayish-white powder, while its common hydrated form is bright blue.
It is used as a fungicide, as an algicide in ponds and pools, and in copper electroplating.
The white anhydrous powder turns blue when it absorbs water, so it is used as a simple test for the presence of water.
