Name the gas evolved when zinc granules are treated/heated with:(a) Hydrochloric acid solution
(b) Sodium hydroxide solution
(a) When zinc granules are treated with hydrochloric acid, hydrogen gas is evolved along with zinc chloride
The equation is given as:
$Zn(s) + 2HCl(aq) → ZnCl_2(aq) + H_2(g)$
(b) When zinc granules are treated with sodium hydroxide, hydrogen gas is evolved along with sodium zincate
The equation is given as:
$Zn(s) + 2NaOH(aq) → Na_2ZnO_2(aq) + H_2(g)$
