Subjective Type

Give two chemical equations for each of the following: (a) Reactions of nitric acid with non-metals (b) Nitric acid showing as acidic character (c) Nitric acid acting as oxidizing agent

Solution

(a) Reaction of nitric acid with non-metal:
$$C+ 4HNO_3 \longrightarrow CO_2 + 2H_2O + 4 NO_2$$
$$S+ 6 HNO_3 \longrightarrow H_2SO_4 + 2H_2O + 6 NO_2$$
(b) Nitric acid showing acidic character:
$$K_2O + 2HNO_3 \longrightarrow 2 KNO_3 + H_2O$$
$$ZnO + 2HNO_3 \longrightarrow Zn(NO_3)_2 + H_2O$$
(c) Nitric acid acting as oxidizing agent
$$P_4 + 20HNO_3 \longrightarrow 4 H_3PO_4 + 4H_2O + 20NO_2$$
$$3Zn + 8HNO_3 \longrightarrow 3 Zn(NO_3)_2 + 4H_2O + 2NO$$
