Because complete and rigorous solution is time consuming, here only procedures for calculating the pH at several convenient points in a titration of 0.1 M sodium carbonate with 0.1 M hydrochloric acid (Figure 1) are covered briefly.he solution now contains an equimolar mixture of carbonate and bicarbonate. We can calculate the pH at this point by rearranging Equation (3) to [H+] = [HCO-3] K2 [CO2-3 ] (14) Since the bicarbonate and carbonate concentrations are equal, the hydrogen ion concentration is equal to K2, and the pH is 10.3.
