Question

How does the end point of a titration differ from the equivalence point?

Answer 1

The answer is based on the physical chemistry experiments carried out in the lab where the answer lies in the fact that when does these two occur during the titration. The answer lies in the name of the given terms.

Complete Answer:
In the lower classes of physical chemistry, we are familiar in carrying out some of the physical chemistry experiments which even include the titrimetric analysis that is based on the titration process.
We shall recall these terms so that we can approach the required answer.
- Titration is the quantitative chemical analysis which is used for the determination of concentration of the identified analyte.
- In the process of titration two important stages are known : the end point and the equivalence point.
Here, the differences in these two quantities can be seen in the table below,

Equivalence point	End point
It is the point at which the added titrant will be chemically equivalent to sample analyte.	The point at which the indicator added changes its colour.
This value comes before the end point is reached.	This value comes at an end after the equivalence point.
Weak acids can have multiple equivalence points.	Weak acids usually have only one endpoint.

Note:
In this process of titration, a reagent which is commonly called as the titrant or titrator is prepared and foiled in burette which acts as the standard solution which is of known concentration and volume and this reagent helps in the determination of concentration of the unknown analyte which is taken in beaker.
