Copper Sulfate

Copper sulfate pentahydrate is a blue crystalline solid. It is not combustible and has a strong, nauseating metallic taste. However, it is odorless. When dehydrated, it turns white. Copper sulfate is made by treating copper with hot concentrated sulfuric acid. The crystal combines with other elements for the preparation of different compounds. In its pure nature, it is used as fungicide. It is also mixed with sodium hydroxide to control fungus in melons and grapes.
