To sketch the curve, you want to have the initial point, the stoich. point and a final point. You can solve for the volume of HCl at the stoich. point since mol of acid=mol of base. If your sketch needs more points, you can choose volumes of HCl more and less than the stoich. point to calculate the pH.
