Question

Select the incorrect statement: When Hydrochloric acid or acetic acid of same concentration are taken, (1) pH of Hydrochloric acid = pH of acetic acid (11) pH of Hydrochloric acid > pH of acetic acid (III) pH of Hydrochloric acid < pH of acetic acid (IV)pH is not related to concentration of acid. (a) Only (111) (b) Both (1) and (IV) (c) Both (II) and (IV) (d) (I), (II) and (IV)​

Answer 1

Answer:

Option D

Explanation:

As acetic acid is weaker the ph would be greater than HCl.

Answer 2

Answer:

D

Explanation:

because the ph increases when OH- ions increases and the pH decreases when H+ions increases
