Question
Name the salt which on hydrolysis forms basic. Give a balanced equation for the following reaction.
Solution
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)
\[\ce{Na2CO3 + 2H2O <=> \underset{weak acid}{H2CO3} + \underset{strong alkali}{2NaOH}}\]
\[\ce{CH3COOK + H2O <=> \underset{weak acid}{CH3COOH} + \underset{strong alkali}{KOH}}\]
