After completing the calculations below, sketch the pH curve for the titration of 25.0 mL of 0.150 M solution of a weak base, B (Kb = 6.8 x 10^-5), with 0.150 M HI. Indicate the pH at (a) the beginning of the titration (0.0 mL titrant) and after the addition of (b) 12.5 mL, (c) 24.0 mL, (d) 24.9 mL, (e) 25.0 mL, (f) 25.1 mL, and (g) 30.0 mL of the titrant. Label the half-neutralization point and the equivalence point on the curve. Select a suitable acid-base indicator.
