WebCalculate the ionization constant of the acid. A sample of a certain monoprotic weak acid was dissolved in water and titrated with 0.125 M NaOH, requiring 16.00 mL to reach the equivalence point. During the titration, the pH after adding 2.00 mL NaOH was 6.912. Calculate Ka for the weak acid. Web15 feb. 2009 · % ionization = (x/1.00) (100) NOTE: if the above answer is not precise enough, the equation: x^2 / (1.00-x) = 4.38x10^-4 must be simplified to a quadratic trinomial which is equal to 0. That must be solved. Of the two roots, only one would work. answered by GK February 15, 2009 A clarifying note here:
