pH of separate solution of four potassiu...

`pH` of separate solution of four potassium salts, `KW,KX, KY` and `KZ` are `7.0, 9.0, 10.0`, and `10.5`, respectively. If each solution is `0.2M`, the strongst acid would be

A

`HW`

B

`HX`

C

`HY`

D

`HZ`

Text Solution

Verified by Experts

The correct Answer is:
A
Lower `pH` means higher `K_(a)` value and thus stronger is the acid.
