    For an acid of known identity just look up the pKa value in tables. If the identity of the acid is unknown the pKa can be determined by potentionmetric titration with a strong alkali. The lower the pKa value the stronger the acid. A strong acid will have a pKa < zero and a very weak acid will have a value of 10.

    It's difficult to believe there are any strong organic acids.

    prepare a solution of known concentration  ---  0.1 M

    the find the pH of the soution.

    lower pH means a stronger acid. . . higher pH means a weaker acid
