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.

MISSED THIS? Read Section 18.4 (Page); Watch KCV 18.4B. Consider the curve shown here for the titration of a weak monoprotic acid with a strong base. Hd 14 12 10 8 6420 80 120 160 40 Volume of base added (mL) The figure shows pH as a function of volume of base added. The pH is measured from 0 to 14 on the y-axis, while the volume of base added is measured from 0 to 160 milliliters on the x-axis. The curve of the plot goes up gradually from pH 2.3 at 0 milliliters to pH 5.8 at 49 milliliters, next the plot goes up steeply to pH 11.8 at 51 milliliters, and finally the plot goes up gradually to pH 12.2 at 160 milliliters. ✓ Correct An equilibrium problem based on the initial concentration and Ka of a weak acid should be solved for aqueous solution of the weak acid. This is true for the initial state of titration, when no base has been addition of a small amount of a strong base turns this solution into a buffer whose pH is calculated in way.
