Question
Data collected during the titration of a 20.0 mL sample of a 0.10 M solution of a monoprotic acid with a solution of NaOH of unknown concentration are plotted in the graph above. [VISUAL] Based on the data, which of the following are the approximate pKa of the acid and the molar concentration of the NaOH?
A.
pKa = 4.7; [NaOH] = 0.050 M
B.✓ Correct
pKa = 4.7; [NaOH] = 0.10 M
C.
pKa = 9.3; [NaOH] = 0.050 M
D.
pKa = 9.3; [NaOH] = 0.10 M
