Question

what is the end point in a titration? the point where the indicator changes color. the point where the reaction is complete. the point where the burette is emptied. the point where moles of acid equal moles of base.

Explanation:

In titration, the endpoint is defined as the point where the indicator used in the titration changes its color. The equivalence point is when the reaction is complete (or moles of acid equal moles of base in acid - base titration), and the burette being emptied is not related to the endpoint concept. So the correct option is the one about the indicator changing color.

Answer:

A. The point where the indicator changes color.
