Sketch the curves for (A) the titration of a typical weak acid (30.0ml of 0.10 M) with a strong base (0.10 M) and (B) the titration of a typical strong base (30.0ml of 0.10 M) with a strong acid (0.10 M). Indicate the approximate pH's at the equivalence points, as well as starting and ending pH's. (you need not actually calculate these pH values, estimate them).
