Subjective Type

Write balanced equations and name the products formed when: (a) Sodium hydrogen carbonate is added to nitric acid (b) cupric oxide reacts with nitric acid (c) zinc reacts with dilute nitric acid (d) concentrated nitric acid is heated

Solution

(a) When Sodium hydrogen carbonate is added to nitric acid sodium nitrate, carbon dioxide and water is formed.

$$NaHCO_3 + HNO_3 \longrightarrow NaNO_3 + H_2O +CO_2$$

(b) When Cupric oxide reacts with dilute nitric acid, it forms Copper nitrate.

$$CuO + 2HNO_3 \longrightarrow Cu(NO_3)_2 + H_2O$$

(c) Zinc reacts with nitric acid to form Zinc nitrate, nitric oxide and water.

$$3Zn + 8HNO_3 \longrightarrow 3Zn(NO_3)_2 + 4H_2O + 2NO$$

(d) $$4HNO_3 \longrightarrow 2H_2O + 4NO_2 + O_2$$
