Properties of Zinc:
Physical properties:
1) Zinc is a bluish white metal.2) It is good conductor of heat and electricity.3) It is ductile and malleable.Chemical properties:
1) Action of air:
Whenever heated in air at 773 K, it burns to generate a white cloud of Zinc oxide that settles to form a wooly flock termed as philosopher’s wool.
2) Action of water:
Pure zinc does not react with water although impure zinc (i.e., Zn-Cu couple) decomposes steam quite eagerly evolving H2 gas.
Zn + H2O (steam) → ZnO + H23) Action of dilute acids:
Pure zinc is not attacked by the dilute acids. Though, impure zinc reacts with dilute acids with the release of H2.
Zn + 2HCl → ZnCl2 + H2↑Zn + H2SO4 → ZnSO4 + H2↑4) Action of concentrated H2SO4:
Zinc reacts with hot concentrate H2SO4 generating ZnSO4.Zn + 2H2SO4 → ZnSO4 + SO2 ↑ + 2H2O5) Action of HNO3:
Zinc reacts with HNO3 at different concentrations and it provides various products.
4 Zn + 10 HNO3 (dil) → 4 Zn(NO3)2 + N2O + 5 H2O Nitrous oxide4 Zn + 10 HNO3 (very dilute) → 4 Zn (NO3)2 + NH4NO3+ 3H2O Ammonium nitrate6) Action of alkalies:
Zinc dissolves in hot NaOH solution creating soluble zincate ion.
Zn + 2NaOH + 2H2O→ Na2ZnO2 + H2O Sodium zincate
