Salt hydrolysis is an acid - base react...

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

A

0.05

B

0.1

C

0.2

D
