One of the problems being encountered by students during Acid-Base titration is the inability to clearly differentiate between equivalence point and endpoint. Both are very important during this type of reaction because they represent two important stages in Acid-base Titration.

Equivalence point simply refers to a point during Acid-base titration when the mole of the titrant i.e., the known concentration, is the same with the mole of the analyte i.e., the unknown concentration. In other words, the equivalence point refers to the point when 1mole of H2SO4 is equal to 1 mole of NaOH during Acid-base titration.

On the other hand, the Endpoint of a chemical reaction is a point that will be noticed after the equivalence point, and it is usually indicated by a change in the color of the solution. At times, the endpoint is just an indicator that the equivalence point has been achieved. At times, you can get multiple equivalence points, but the endpoint usually happens once.
