Chemical Properties of Zinc


Chemical Properties

Zinc dissolves in both acids and alkalis. An alkali is a chemical with properties opposite those of an acid. Sodium hydroxide ("common lye") and limewater are examples of alkalis. Zinc does not react with oxygen in dry air. In moist air, however, it reacts to form zinc carbonate. The zinc carbonate forms a thin white crust on the surface, which prevents further reaction. Zinc burns in air with a bluish flame.

Reactions of Zinc: with air, water, halogens, acids, and bases

Highly flammable
