Refer back to equation (2), and consider carefully whether you could simply have used the pH value of the solution at the very beginning of the titration, before any base had been added, to determine either or both the molar mass and the Ka value. Which of the following is the best conclusion? The initial solution pH depends only on the concentration of the weak acid, so measuring the initial pH is sufficient to determine the concentration. The Ka can then be calculated. The initial solution pH depends only on the Ka of the weak acid, so measuring the initial pH is sufficient to determine the Ka. The concentration can then be calculated. The initial solution pH depends on the both the Ka and the concentration of the weak acid, so measuring the initial pH is insufficient to determine both these unknowns.
