Question

    An acid when added in water, has an active acidity of

    0.099 M and potential acidity of 0.001 M and the total acid concentration is 0.100 M. This acid will be a
    A Weak acid Correct Answer Incorrect Answer
    B Strong acid Correct Answer Incorrect Answer
    C Neutral Correct Answer Incorrect Answer
    D None of the above Correct Answer Incorrect Answer

    Solution

    Active acidity refers to the H+ ion concentration in solution while the un-dissociated acid is considered potential acidity. In case of strong acids, 100 % dissociation occurs when it is added in water which means that the active acidity of the acid will be more. And pH measure active acidity
