Amount of NaOH Initial pH Final pH Combined pH Added 4.65 5.1mL 7.37 6.44 4.62 17mL 8.85 5.50 4.25 6.3mL 8.86 5.36 4.6 7.4mL 8.10 5.82 For each result, calculate the Ka of the final solution (both 25ml allots of Potassium hydrogen phthalate together). Find the average pH and calculate the Ka from the average. SHOW YOUR CALCULATIONS! Solution # pH of solution Ka of solution 1 2 3 4 Average The theoretical Ka of Potassium hydrogen phthalate is 3.9 x 10-6. Calculate the percent error of your Ka compared to the theoretical Ka.
