WebSummary. Plots of acid–base titrations generate titration curves that can be used to calculate the pH, the pOH, the pKa, and the pKb of the system. The shape of a titration curve, a plot of pH versus the amount of acid or base added, provides important information about what is occurring in solution during a titration. WebChoose the closest answer. 2.85 x 10-3. The concentration of the HCl solution is between. 0.100 M + 0.200 M. An alternative way of calculating the molarity of the HCl solution is to use the pH of the solution before the titration. The pH = -log ( [H+]) and thus the concentration of HCl is given by [HCl] = 10-pH.
