The compound is used as a mordant in dyeing and as a latex coagulant. It also is used as an acid catalyst and as an analytical standard for zinc.
Zinc nitrate is prepared by reacting zinc metal, zinc oxide or zinc hydroxide with nitric acid followed by crystallization. The salt is obtained as hexahydrate:
Zn + 2HNO3 → Zn(NO3)2 + H2
ZnO + 2HNO3 → Zn(NO3)2 + H2O
Zn(OH)2 + 2HNO3 → Zn(NO3)2 + 2H2O
The salt also is sold commercially in the form of fused pieces and technical flakes containing about 20% and 25.6% water, respectively.
