Chapter 7: Q2p (page 158)

Distinguish between the terms equivalence point and end point.

Short Answer

Expert verified

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

01

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.

02

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.
