AIPMT MAIN 2008 Chemistry pH and pOH MCQ Question
Type: MCQ-numerical-Medium-Class 11
Equal volumes of three acid solutions of pH 3, 4 and 5 are mixed in a vessel. What will be the H⁺ ion concentration in the mixture?
A
1.11 × 10⁻³ M
B
1.11 × 10⁻⁴ M
C
3.7 × 10⁻⁴ M
D
3.7 × 10⁻³ M
Correct Answer
Option C
Detailed Explanation
The concentration of H⁺ ions from each solution is 10⁻³ M, 10⁻⁴ M, and 10⁻⁵ M respectively. When mixed in equal volumes, the average concentration is (10⁻³ + 10⁻⁴ + 10⁻⁵)/3 = 3.7 × 10⁻⁴ M.
