1) When visually monitoring a titration with an indicator, which of the following indicates you should begin to add smalle amounts of titrant (NaOH) to your analyte (KHP) solution? A. When the volume of titrant added is close to half the volume needed to reach the equivalence point. B. When the change in color of the solution begins to persist for longer periods of time. C. When the pH of the solution begins to increase rapidly. D. When the volume of titrant added is close to the volume needed to reach the equivalence point.

A. When the volume of titrant added is close to half the volume needed to reach the equivalence point.
B. When the change in color of the solution begins to persist for longer periods of time.
C. When the pH of the solution begins to increase rapidly.
D. When the volume of titrant added is close to the volume needed to reach the equivalence point.
Expert Solution
Step 1
When are performing acid - base titratiion the reaction stoichiometrically completed at equivalent point , at that point sharp pH change occur by adding a drop of titrant. The color transition occur near at equivalent point during titration.
