(i) They react with metals to give out hydrogen gas e.g.,
Zn + 2HCl → ZnCl2 + H2
Zinc + Hydrochloric acid → Zinc Chloride + Hydrogen
(ii) They react with bases to form salt and water e.g.,
2NaOH + H2SO4 → Na2SO4 + 2H2O
Sodium hydroxide + Sulphuric acid → Sodium sulphate Water
(iii) They react with metal carbonates to liberate CO2 gas
Na2CO3 + 2HCI → 2NaCI + H2O + CO2
Sodium carbonate + Hydrochloric acid → Sodium chloride + Carbon dioxide
