Question- After completing the calculations below, sketch the pH curve for the titration of 25.0 mL of 0.150M solution of a weak base, B = (Kb = 6.8 x 10^-5), with 0.150M 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) 25.0mL, (f) 25.1 mL, and (g) 30.0 mL of the titrant.
