Label the pH scale below, indicating theacidity of a solution in the given regions.

Indicate the color of phenolphthalein withinthe pH ranges shown below.

Why is phenolphthalein an appropriate indicatorfor a weak acid-strong base titration?

A. Theequivalence point of the titration and the phenolphthalein endpoint differ by less than one pH unit, so the change in colorassociated with the indicator endpoint will very closely indicatethe chemical equivalence point.

B. The equivalencepoint and the end point are both at a pH of 7, so the indicatorwill change color at the equivalence point.

C. The equivalencepoint and the end point are both at a pH of 10, so the indicatorwill change color at the equivalence point.
