Arrange the aqueous solutions of the following salts in the increasing order of their pH . I . CuSO 4 II . NaCN III . KCl
Options
- AI < II < III
- BI < III < II
- CIII < II < I
- DII < III < I
Correct answer
B. I < III < II
Step-by-step solution
The pH of the solutions will be as given below: I .   CuSO 4 :   Salt of strong acid and weak base  pH < 7 II .   NaCN :   Salt of weak  acid and strong base   pH > 7   III .   KCl :  Salt of strong acid and strong base   pH = 7
