Copper sulfate is a sulfate salt of copper. It can be used to prevent the growth of algae. This forms as large, bright blue crystals containing five molecules of water (CuSO4∙5H2O) and is also known as _blue vitriol_. The anhydrous salt is created by heating the hydrate to 150 °C (300 °F). Cupric sulfate is used primarily for agricultural purposes, as a pesticide, germicide, feed additive, and soil additive. Some of its secondary uses are as a raw material in the preparation of other copper compounds, as a reagent in analytic chemistry, as an electrolyte for batteries and electroplating baths.
