In titration, what is the purpose of the indicator?

Step 1: Understand that titration is a method used to determine the concentration of a solution.
Step 2: Know that during titration, two solutions are mixed together.
Step 3: Realize that the reaction between the two solutions will reach a point called the 'endpoint'.
Step 4: The endpoint is when the reaction is complete, and no more of one solution can react with the other.
Step 5: The indicator is a special substance added to the solution that changes color at the endpoint.
Step 6: When the color change happens, it signals that the titration is finished.

Indicator in Titration – An indicator is a substance that changes color at a specific pH level, signaling the completion of a titration.
