Question

What is the equivalence point in a titration? What is the endpoint in a titration? How are they different?

Answer 1

The endpoint refers to the point at which the indicator changes colour in a colourimetric titration.

The equivalence point, or stoichiometric point, of a chemical reaction is the point at which chemically equivalent quantities of acid and base have been mixed.

Equivalence point is the actual point where the reaction has just been completed and refers to the stoichiometric quantities of reactants.So equivalence point represents the end point representing accurately the point at which reactants have just competely reacted - no extra needs to be added to get the indicator to change.
