Answer

(a) Acidic nature

  1. Mg + H2SO4 (dil.) ⟶ MgSO4 + H2 ↑
  2. Zn + H2SO4 (dil.) ⟶ ZnSO4 + H2 ↑

(b) Oxidising agent

  1. C + 2H2SO4 ⟶ CO2 + 2H2O + 2SO2 ↑
  2. Zn + 2H2SO4 ⟶ ZnSO4 + 2H2O + SO2 ↑

(c) Dehydrating Nature

  1. HCOOH→Conc. H2SO4CO+H2O\text{HCOOH} \xrightarrow{\text{Conc. H}2\text{SO}4} \text{CO} + \text{H}_2\text{O}
  2. C2H5OH ethyl alcohol→170°CConc. H2SO4[excess]C2H4ethene↑+H2O\underset{\text{ ethyl alcohol}}{\text{C}2\text{H}5\text{OH}} \xrightarrow[170\degree\text{C}]{\text{Conc. H}2\text{SO}4\text{[excess]}} \underset{ \text{ethene}}{\text{C}2\text{H}4} ↑ + \text{H}_2\text{O}

(d) Non-volatile Nature

  1. NaCl + H2SO4 ⟶ NaHSO4 + HCl
  2. KCl + H2SO4 ⟶ KHSO4 + HCl
