In order to determine the Ka of a weak, monoprotic acid, a student measured the pH of a solution of this weak, monoprotic acid to be 3.617. Based on the full- neutralization titration portion of the experiment, it was found that the total molar concentration of this acid solution was 2.632 M. Using these measurements, what would be the Ka for this weak, monoprotic acid? Ka X 10-7 Please enter as your answer only the underlined numerical part of the Ka above. Round your answer to two decimal places.

All of the acids start out at 0.1 M concentration and 25.0 mL volume. Choose all of the correct statements about these titration curves from the cholces below. The titration curve labelled "D" is generated by the strongest acid in the series. In the curves shown above the stronger the acid the less NaOH required for neutralization. The stronger the acid the more important is the pKa of the Indicator used for titration. The Ka of the acid which generates curve "C" is about 103 The weaker the acid the lower the pH of the neutralization point. The acid which generates curve "D" has the highest neutralization-point pH in the series.
