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

A

`5%`

B

`10%`

C

`20%`

D

None of these

Text Solution

Verified by Experts

The correct Answer is:
B
Degree of hydrolysis for WA - WB (h)
`= sqrt((K_(w))/(K_(a)xxK_(b)))`
does not depend on the concentration of salt So h will be the same.

Salt hydrolysis is an acid - base reaction of cation or anion or both ions of salt with water . The resultant solution after hydrolysis may be acidic , basic or neutral . The anion X^(-) which is weaker base than OH^(-) and which has its conjugate acid HX stronger than water but weaker than H_(3)O^(+) shows the phenomenon of hydrolysis , e.g CH_(3)COO^(-) , NO_(2)^(-) , CN^(-) etc. The cation M^(+) which is weaker acid than H_(3)O^(+) and which has its conjugate base MOH stronger than water but weaker than OH^(-) shows the phenomenon of hydrolysis , e.g N_(2)H_(5)^(+), C_(6)H_(5)NH^(+),NH_(4)^(+) etc .
