Final answer:
The end point is the point at which the indicator changes color, while the equivalence point is the point at which the stoichiometric amount of acid and base have reacted exactly.
Step-by-step explanation:
In an acid-base titration, the end point and the equivalence point are two distinct concepts. The end point is the point at which the indicator changes color, indicating that the reaction has reached its endpoint. It is easily visible and can be determined based on the color change.
The equivalence point, on the other hand, is the point at which the stoichiometric amount of the acid and the base have reacted exactly. It is determined based on the chemical reaction that takes place.
