Chapter 19, Problem 72A

Interpretation Introduction

Interpretation : The possibility of the end point of a titration is to be explained.

Concept Introduction : Titration is the process of introducing a measured amount of a solution with a known concentration to a solution with an unknown concentration.

Answer to Problem 72A

The endpoint of a titration is recognized by the color change of the indicator used in the titration.

Explanation of Solution

The point at which neutralization occurs is called the equivalence point.

The titration's end point occurs when the indicator's color changes.

An indicator is a chemical substance that changes color when an acid or base is present.

With the help of the indicator’s color change, the endpoint of the titration is detected.
