8.5 Acid-Base Titrations
BeginnerMCQGraphical18.4k
A 2D line graph displaying a titration curve with bare axes and light grid lines. The horizontal axis is labeled 'Volume of 0.100 M NaOH added (mL)' with values from 0 to 40 marked at increments of 5. The vertical axis is labeled 'pH' with values from 0 to 14 marked at increments of 2. A single solid black curve begins at (0, 2.0), rises slightly through a flat buffer plateau centered at (7.5, 3.5), rises sharply through a first vertical inflection region centered at (15.0, 5.5), continues through a second flat buffer plateau centered at (22.5, 7.2), rises sharply through a second vertical inflection region centered at (30.0, 10.0), and levels off horizontally at a pH of approximately 12.0 near 40 mL. No other curves, text, or annotations appear.
Titration curve for the unknown acid titrated with \(0.100\text{ M NaOH(aq)}\).
A student titrates a sample of an unknown acid with \(0.100\text{ M NaOH(aq)}\) using a \(\text{pH}\) sensor. The resulting titration curve is shown below.

Based on the titration curve, which of the following claims about the unknown acid is correct?
