The pH of 0.1 M solution of the following salts increases in the order.

A

`NaCl lt NH_(4)Cl lt NaCN lt HCl`

B

`HCl lt NH_(4)Cl lt NaCl lt NaCN`

C

`HCN lt NH_(4)Cl lt NaCl lt HCl`

D

`HCl lt NaCl lt NaCN lt NH_(4)Cl`

Text Solution

Verified by Experts

The correct Answer is:
B
NaCN is basic salt, has highest pH while HCl has lowest pH. NaCl is neutral salt has pH=7 while `NH_(4)Cl` is acidic salt, has pH less than 7.
