Question

The pH of a sample of hydrochloric acid is 2. The pH of this sample when diluted by adding some water will be (1) more than 7
(2) more than 2 but less than 7
(3) unchanged (4) less than 2 but more than 0

Answer 1

Answer:

Option (2) is correct.

Explaination:

When acid is diluted, its concentration of H+ ions decreased per unit volume .Thus, making the acid more basic. Thus its pH increases.
