Questions And Answer | Back Directory | [Physical Properties]
The hexahydrate, Zn(NO3)2•6H2O, is a colorless and odorless crystalline solid; tetragonal structure; density 2.065 g/cm3 at 15°C; melts at 36.4°C; loses all its water of crystallization between 105 to 131°C; very soluble in water, about 184 g/100mL water at 20°C; the aqueous solution acidic, the pH of a 5% solution is about 5.1; also very soluble in alcohol.
The trihydrate, Zn(NO3)2•3H2O consists of colorless needles; melts at 45.5°C; very soluble in water, 327 g/100mL at 40°C.
| [Uses]
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.
| [Preparation]
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.
