Question

For $0.1MC{H}_{3}COON{H}_4$ salt solution, given $K_{a_{C{H}_{3}COOH}}=K_{b_{N{H}_{4}OH}}=2\times {10}^{-5}$. In this case, the degree of hydrolysis of cation and anion is

• A. exactly the same
• B. slightly different
• C. can't say
• D. different but can be taken as approximately the same

Answer 1

The correct option is A exactly the same

Both the ions are produced from the same salt. They have the same initial concentrations. Also, they have same dissociation constants. Hence, they have exactly the same degree of hydrolysis.
