`HA` is a weak acid and `BOH` is a weak base. For which of the following salts the extent of hydrolysis is independent of the concentration of the salt in its aqueous solution

A

`NaA`

B

`NaB`

C

`BCl`

D

`BA`

Text Solution

Verified by Experts

The correct Answer is:
D
The extent of the hydrolysis `(h)` of the salt made by weak acid and weak base is independent of the concentration of salt.
`underset(weak acid)(HA)+underset(weak base)(BOH) rarr BA+H_(2)O`
`K_(h)=` hydrolysis constant `=(K_(w))/(K_(a)K_(b))`
