Question

Distinguish between the terms equivalence point and end point.

Short answer

The equivalence point is a physical location that signifies that the titration is complete; that is, the amount of analyte equals the amount of titrant.

End point, on the other hand, is frequently used to estimate equivalence point based on color change.

Step-by-step solution

Define terms equivalence point.

An equivalency point is a word used in the titration process. It technically applies to any acid-base or neutralization reaction.

Now distinguish the term.

In titration, the equivalence point is the point at which the required volume of titrant for complete titration is attained,

• i.e. when the analyte and titrant amounts are chemically comparable.

• End point, on the other hand, is a method of estimating chemical equivalence based on a physical change, such as a change in hue.

• In a titration, an appropriate indicator or dye is employed to detect the end point

The main distinction between equivalency and endpoint is that the former refers to the point at which a chemical process comes to a stop, whilst the latter refers to the point at which a system's colour changes.

Equivalence Point vs. Endpoint Although the endpoint and the equivalence point are sometimes confused, they are not the same.
