STANDARD Chemistry pH Calculations MCQ Question
Type: MCQ-numerical-Medium
Solution of a monobasic acid has a pH = 5. If one mL of it is diluted to 1 litre, what will be the pH of the resulting solution?
A
3.45
B
6.96
C
8.58
D
10.25
Correct Answer
Option B
Detailed Explanation
The initial [H⁺] is 10⁻⁵ M. After dilution, the concentration becomes 10⁻⁸ M. Considering the contribution of [H⁺] from water, the total [H⁺] is approximately 1.1 × 10⁻⁷ M, giving a pH of 6.96.
