Copper sulfate is also known as blue vitriol, this substance was made by the action of sulfuric acid on elemental copper. The bright-blue crystals are soluble in water and alcohol. Mixed with ammonia, copper sulfate was used in liquid filters. The most common application for copper sulfate was combining it with potassium bromide for making copper bromide bleach for intensification and toning. Some photographers used copper sulfate as a restrainer in ferrous sulfate developers that were used in the collodion process.

Copper Sulfate is a nutrient supplement and processing aid most often used in the pentahydrate form. This form occurs as large, deep blue or ultramarine, triclinic crystals, as blue granules, or as a light blue powder. The ingredient is prepared by the reaction of sulfuric acid with cupric oxide or with copper metal. May be used in infant formula. It is also termed cupric sulfate.

Copper(II) sulfate may be employed for the following studies:

•As a catalyst for the acetylation of alcohols and phenols under solvent-free conditions.

•To compose the electrolyte for the electrodeposition of Cu-Zn-Sn precursors, required for the preparation of Cu2ZnSnS4 (CZTS) thin films.

•As a Lewis acid catalyst for the dehydration of alcohols.5
