  • question_answer
    Equal volumes of two HCl solutions of \[pH=3\] and were mixed. What is the pH of the resulting solution?

    A) 3.5

    B) 4.0               

    C) 4.5

    D) 3.3

    Correct Answer: D

    Solution :

    [d] When equal volumes are taken, the concentration becomes half.
                \[\therefore \]      \[[{{H}^{+}}]=\frac{1}{2}({{10}^{-3}}+{{10}^{-5}})=505\times {{10}^{-6}}\]
                \[\therefore \]      \[pH=3.3\]
