    Read the given statements and mark the correct option.
    Statement 1: A solution of pH = 1 has hydrogen ion concentration 3 times than that of solution of pH = 3.
    Statement 2: \[pH=-\log \frac{1}{[{{H}_{3}}{{O}^{+}}]}\]
     

    A) Both statements 1 and 2 are true and statement 2 is the correct explanation of statement 1.

    B) Both statements 1 and 2 are true but statement 2 is not the correct explanation of statement 1.

    C) Statement 1 is true and statement 2 is false.

    D) Both statements 1 and 2 are false.

    Correct Answer: D

    Solution :

    A solution of pH = 1 has hydrogen ion concentration 100 times than that of a solution of pH = 3 \[pH=-\log [{{H}_{3}}{{O}^{+}}]=log\frac{1}{[{{H}_{3}}{{O}^{+}}]}\]
