Current Question (ID: 8525)

Question:

$\text{The percentage degree of hydrolysis of a salt of weak acid (HA) and weak base (BOH) in its } 0.1 \text{ M solution is found to be } 10\%. \text{ If the molarity of the solution is } 0.05 \text{ M, the percentage hydrolysis of the salt should be -}$

Options:

1. $5\%$
2. $10\%$
3. $20\%$
4. $\text{None of the above}$

Solution:

$\text{Hint: Percentage of hydrolysis of the salt remain same.}\text{The degree of hydrolysis of a salt of weak acid and weak base is independent of the concentration of salt. So the percentage of hydrolysis of the salt is } 10\%.$
