Give a balanced chemical equation for each of the following:

(i) Action of conc. Nitric acid on Sulphur.

(ii) Catalytic oxidation of Ammonia.

(iii) Laboratory preparation of Nitric acid.

(iv) Reaction of Ammonia with Nitric acid.

Answer

(i) S + 6HNO3 [conc.] ⟶ H2SO4 + 2H2O + 6NO2

(ii) 4NH3+5O2→800°CPt.4NO+6H2O+Δ4\text{NH}_3 + 5\text{O}_2 \xrightarrow[800 \degree \text{C}]{\text{Pt.}} \text{4NO} + \text{6H}_\text{2}\text{O} + \Delta

(iii) KNO3 + H2SO4 [conc.] →<200°C\xrightarrow{\lt 200 \degree\text{C}} KHSO4 + HNO3

(iv) NH3 + HNO3 ⟶ NH4NO3
