Description

Description générale

Anhydrous form of copper sulfate occurs as mineral hydrocyanite. It exhibits a rhombic crystalline morphology. It decomposes to its oxide at temperatures above 600^oC. Hydrate of CuSO₄ is prepared by the addition of dilute sulfuric acid on copper (II) oxide or copper (II) carbonate, blue triclinic crystals of pentahydrate are formed upon crystallization. In industrial preparation of CuSO₄, a hot mixture of dilute sulfuric acid and scrap copper is exposed to air flow.

Application

This anhydrous salt may be used in the electroplating and mining industries and to preserve wood in combination chromium and arsenic.
