Products Description of Copper(II) sulfate pentahydrate CAS#7758-99-8
Copper(II) sulfate pentahydrate is commonly known as blue vitriol. It is an odorless blue crystal that dissolves easily in water, and is also soluble in methanol and glycerol, while only slightly soluble in ethanol. It is highly toxic and non-combustible, with a nauseating metallic taste, and turns white when it loses water (dehydrates).
