Zinc nitrate is a highly deliquescent substance which is usually prepared by dissolving zinc in nitric acid. It can be used as a mordant in dyeing. An example reaction gives a precipitate of zinc carbonate: Zn(NO₃)₂ + Na₂CO₃ → ZnCO₃ + 2 NaNO₃.

Conditions/substances to avoid are: reducing agents, organic materials, metal powders, heat and flame, cyanides, sodium hypophosphite, tin(IV) chloride, phosphorus, thiocyanates, carbon, and sulfur. Its relative molecular mass is 189.

Zinc nitrate is soluble in both water and alcohol.
