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.
