The end point of a titration is defined as the volume of titrant added, while the equivalence point is the volume required for complete reaction with the analyte. By choosing the proper , scientists can minimize the difference in these two numbers, allowing more accurate measurements in the lab.

indicator

Explanation:

Indicators are the weak organic dyes which shows different colors in acidic and basic mediums.

Due to the fact that a noticeable pH change occurs near the equivalence point of acid-base titrations, an indicator can be used to signal the end point of a titration.

Therefore, choosing the proper indicator, scientists can minimize the difference in these two numbers, allowing more accurate measurements in the lab.

INDICATOR

Explanation:

A particular indicator is chosen because it is designed to change color very close to the equivalence point of a reaction, thus making the end point of a titration very close to the equivalence point.
