What is the difference between equivalent point and end point in analytical chemistry?

Answer 1

The equivalence point is the point in a titration when the amount of added standard reagent is chemically equal to the amount of analyte.

The end point is the point in a titration when a physical change occurring immediate after the equivalence point

Answer 2

The stoichiometric point, of a chemical reaction occurs during a chemical titration when the amount of titrant added is equal, to the amount of analyte present in the sample, where as.

The end point (similar, but not the same as the stoichiometric point) refers to the point at which the indicator changes color in a colorimetric titration.

Answer 3

The endpoint is when the solution changes colour in a titration.

The equivalence point is the point at which exactly the same amount of titrant is added as the (stoechiometric) amount of analyte, present in the sample to be analysed.

If there is a steep, sudden increase in titration curve at that point then it can accurately be detected by an approprate indicator.

[The role of indicator is to show the endpoint as close as possible at the equivalence point]

Answer 4

In analytical chemistry, an equivalent point is the point in a titration where the amount of titrant added is stoichiometrically equivalent to the amount of analyte present. The end point, on the other hand, is the point at which a color change or some other indicator signals that the reaction is complete. The end point may not always coincide with the equivalent point, depending on the nature of the reaction and the indicator used.

Answer 5

The term end point is used for colorimetric titrations; but practically these two terms are synonyms.
