Consider the following titration curves for two weak acids (see the figures (Figure 1), (Figure 2)), both titrated with 0.100 M NaOH.
Part A
Which of the two acid solutions is more concentrated?
Acid (a) is more concentrated.
Acid (b) is more concentrated.
Both acids have the same concentration.
Part B
Which of the two acids has the larger Ka?
Acid (a) has the larger Ka.
Acid (b) has the larger Ka.
Both acids have the same Ka.
