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

Solution

Hydrochloric acid is a strong acid but on the addition of water, its hydrogen ion concentration decreases so its pH will change. pH will become more than 2 but less than 7.

Hence, the correct answer is option 2.
