Question 13

Give equations for the decomposition of a metallic (i) chloride (ii) nitrate with conc. H2SO4.

Answer

(i) Decomposition of a metallic chloride —

NaCl+H2SO4[conc.]→<200°CNaHSO4+HCl\text{NaCl} + \text{H}_2\text{SO}_4 [\text{conc.}] \xrightarrow{\lt 200 \degree\text{C}}\text{NaHSO}_4 + \text{HCl}

(ii) Decomposition of a metallic nitrate with conc. H2SO4 —

NaNO3+H2SO4[conc.]→<200°CNaHSO4+HNO3\text{NaNO}_3 + \text{H}_2\text{SO}_4 [\text{conc.}] \xrightarrow{\lt 200 \degree\text{C}}\text{NaHSO}_4 + \text{HNO}_3
