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.
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.
