Category: Endpoint VS Equivalence

Endpoint Equivalence Point The point at which the indicator changes color. The point at which the titrant and the analyte in the sample are chemically identical. Following the equivalency point. This occurs before the endpoint. Weak acids can only have one terminal. Weak acids can have numerous sites of equivalency. It may not always indicate where the response terminates. It indicates where the reaction finishes. It appears either at the equivalence point or after the equivalent point. It appears either near or before an endpoint.

The equivalence point is also known as a stoichiometric point in the titration. During titration, the point at which the added titrant is chemically equivalent to the analyte in the sample is called the equivalence point. 

The endpoint in titration refers to the point at which the indicator changes colour in the colourimetric titration. For example, in complexometric titration, if Eriochrome Black T is used as an indicator, then at the endpoint, colour changes from wine red to blue.

Titration is a technique used in analytical chemistry to determine the concentration of unknown solutions by using solutions of known concentration. Solution of known concentration is known as titrant while the solution of unknown concentration is known as analyte in titration technique.

Endpoint and equivalence point are the two terminologies that are used in analytical chemistry in titrations. Titration is the volumetric analysis of a sample. This article explains these concepts along with the key differences between endpoint and equivalence point. Endpoint and equivalence points are two different stages that occur in the process of titration. An…
