Question

Equivalence point is the point where equal number of moles of acid and the number of moles of base that have been mixed together are equal. In other words, it is a point in titration at which the amount of titrant added is just enough to completely neutralize the analyte solution. At the equivalence point in an acid-base titration, moles of base = moles of acid and the solution only contains salt and water.

End point is the point at which the indicator being used in such a reaction changes color.
Often, the indicator color change in an acid base titration is not observed AT the equivalence point, but once the equivalence point has been exceeded (i.e. once there is an imbalance of acid or base). This is why equivalence point and end point are not necessarily 100% identical.

Answer 1

The equivalence point in an acid-base titration is the point at which equal moles of acid and base have been mixed, resulting in complete neutralization of the analyte solution. At this point, the solution contains only salt and water.

The end point, on the other hand, is the point at which the indicator used in the titration changes color. The end point is usually reached when the equivalence point has been exceeded, creating an imbalance of acid or base. This is why the equivalence point and end point are not necessarily identical in an acid-base titration.
