Description

Nickel Carbonate
Green crystals that melting at *6°C (decomposes); soluble in acid,
insoluble in water; used in electroplating, as a catalyst production for
organic chemical manufacture, petroleum refining and edible oil hardening.

From the industrial perspective, the most important nickel carbonate is
basic nickel carbonate with the formula Ni4CO3(OH)6(H2O)4. Simpler carbonates, ones more likely encountered in the laboratory, are NiCO3 and 
its hexahydrate.

All are paramagnetic green solid containing Ni2+ cations. The basic carbonate
is an intermediate in the hydrometallurgical purification of nickel from its ores
and is used in electroplating of nickel.
