Question

Which of the following is not a mineral acid?

• A. Hydrochloric acid
• B. Citric acid
• C. Sulphuric acid
• D. Nitric acid

Answer 1

The correct option is B Citric acid

Mineral acids give the ions in an aqueous solution. $HCl$ gives hydrogen and chloride ions. Sulphuric acid gives hydrogen ions and sulphate ions. Nitric acid ionizes to give hydrogen and nitrate ions. Citric acid is a mild acidic organic compound $C_6{H}_8{O}_7$, which does not give any ions.

$HCl⟶H^{+}+{Cl}^{-}{H}_2{SO}_4⟶{2H}^{+}+{SO}_4^{2-}{HNO}_3⟶H^{+}+{NO}_3^{-}$
