ReactivityReacts with acids to produce hydrogen gas. Forms oxides when heated in air.
Corrosion ResistanceZinc exhibits excellent corrosion resistance and is commonly used as a protective coating.
Alloy FormationForms alloys with other metals such as copper (brass) and aluminum (zinc-aluminum alloy).
Reducing AgentCan act as a reducing agent in certain chemical reactions, such as with copper oxide.
Formation of CompoundsForms various compounds such as zinc chloride (ZnCl2), zinc sulfate (ZnSO4), and zinc oxide (ZnO).
Amphoteric NatureExhibits an amphoteric nature, meaning it can react with both acids and bases.

Now before let's check out the reaction:

zinc (zn) Chemical Reactions

Reaction DescriptionChemical EquationInterpretation
Zinc and Hydrochloric Acid (HCl)Zn+2HClZnCl2+H2Zinc reacts with hydrochloric acid to produce zinc chloride and hydrogen gas.
Zinc and Sulfuric Acid (H2SO4)Zn+H2SO4ZnSO4+H2Zinc reacts with sulfuric acid to form zinc sulfate and hydrogen gas.
Zinc Oxide (ZnO) and Hydrogen Gas (H2)ZnO+H2Zn+H2OZinc oxide reacts with hydrogen gas to produce zinc and water vapor.
Zinc and Copper(II) Sulfate (CuSO4) SolutionZn+CuSO4ZnSO4+CuZinc displaces copper from copper sulfate solution to form zinc sulfate and copper metal.
Zinc and Nitric Acid (HNO3)3Zn+8HNO33Zn(NO3)2+2NO+4H2OZinc reacts with nitric acid to produce zinc nitrate, nitrogen dioxide gas, and water.
Zinc and Oxygen (Combustion Reaction)2Zn+O22ZnOZinc reacts with oxygen in the air during combustion to form zinc oxide.
