Question

Name the salt which on hydrolysis forms basic. Give a balanced equation for the following reaction.

Answer 1

Salts from strong bases like NaOH and KOH, as well as weak acids like H₂CO₃ and CH₃COOH, hydrolyse in water to form alkaline solutions. These solutions have a pH greater than 7.

Examples: Sodium carbonate (Na₂CO₃), potassium acetate (CH₃COOK)

\[\ce{Na2CO3 + 2H2O <=> \underset{weak acid}{H2CO3} + \underset{strong alkali}{2NaOH}}\]

\[\ce{CH3COOK + H2O <=> \underset{weak acid}{CH3COOH} + \underset{strong alkali}{KOH}}\]
