How would you determine whether it is a strong acid or a weak acid? (c) If the substance is a weak acid, how would you determine the value of Ka for the substance? (d) Suppose the substance were a weak acid and that you are also given a solution of NaOH(ag) of known molarity. What procedure would you use to isolate a pure sample of the sodium sal: of the substance? (e) Now suppose that the substance were a base rather than an acid. How would you adjust the procedures in parts (b) and (c) to determine if the substance were a strong or weak base. and. if weak, the value of Kb?
