What happens when zinc granules are treated with dilute solution of $H_2SO_4, HCl, HNO_3, NaCl and NaOH$ , also write the chemical equations if reaction occurs.

Answers (1)

When zinc granules reacts with dil $H_{2}SO_{4}$ , displacement reaction takes place leading to the formation of $ZnSO_{4}$ liberating $H_{2}$ gas

$Zn (s) + H_2SO_4 (aq) \rightarrow ZnSO_4 (aq) + H_2 (g)$

When Zinc granules reacts with dil. HCl, displacement reaction takes place leading to the formation of $ZnCl_2$ liberating $H_{2}$ gas

$Zn (s) + 2HCl (aq) \rightarrow ZnCl_2 (aq) + H_2 (g)$

When Zinc granules reacts with dil $HNO_3$ it leads to the formation of Zinc nitrate evolving $H_2O$ and nitrous oxide

$4Zn(s) +10 HNO_3 (aq)\rightarrow 4Zn(NO_3)_2 (aq) + 5H_2O(l) + N_2O (g)$

When Zinc granules reacts with NaCl there will not be any reaction

When Zinc granules reacts with NaOH solution

$Zn(s) + 2NaOH (aq) \rightarrow Na_2ZnO_2 (aq) + H_2 (g)$
