What is difference between equivalence point and end point in the titration ?

Equivalence point is where the CHEMISTRY tells you when neutralization has occurred. The end point is where the indicator tells you where neutralization occurred. So you want the end point and the eq point to be the same if possible. That usually isn't possible to be EXACT but you can get it so closely that the titration error is negligible.

The equivalence point and the end point are terms used in the context of titration, which is a technique used to determine the concentration of a substance in a solution.

The equivalence point refers to the point at which the stoichiometrically equivalent amounts of reactants have reacted completely. It is the theoretical point at which the reaction is completed, assuming that the reaction proceeds exactly according to the balanced equation. At the equivalence point, all the reactants have been consumed, and the reaction has reached a state of chemical equivalence.

The end point, on the other hand, is the point at which an indicator or another signal reveals that the reaction has reached its endpoint or completion. This is usually observed visually through a color change in the indicator. The end point is the practical point at which the experimenters decide to stop the titration because they believe that the reaction has reached its completion.

It is important to note that the end point may not always exactly coincide with the equivalence point. This can happen due to various factors, such as the presence of impurities, incorrect concentration of the titrant, or errors in the experiment. Consequently, the end point is an approximate estimation of the equivalence point and may introduce some degree of error in the final result. To minimize this error, careful observation and multiple trials are recommended.
