Assertion (A): `pH` of `HCI` solution is less than that of acetic acid of the some concentartion.
Reason (R) : In equimolar solution, the number of titrable protons present in `HCI` is less than that present in acetic acid.

Options

A. If both (A) and (R) are correc, and (R) is the correct explanation of (A).
B. If both (A) and (R) are correct but (R) is not the correct explanation of (A).
C. If (A) is correct, but (R) is incorrect.
D. If (A) is incorrect, but (R) is correct.

Answer

C

Explanation

`(A)` is correct because `HCI` is a strong electrolyte resulting in higher `[H^(o+)]` (and less `pH)` then acetic acid. `(R)` is wrong, `HCI` will produce more protons than acetic acid at same concentration.
