Whether a negative value of pH is possible

A

Yes

B

No

C

Some times

D

None of these

Text Solution

Verified by Experts

The correct Answer is:
B
The degree of dissociation of an acid or base decreases as we increase the concentration, say `gt` 1M . So the actual concentration of `[H^(+)]` will not increase and hence pH can not be less than zero.
