Product Application of Copper(II) sulfateCAS#7758-98-7

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.
