ANSWER
The role of the indicator is to help us determine the endpoint of the reaction
Step-by-step explanation
Titration is defined as a technique where a solution of a known concentration is used to determine the concentration of an unknown solution.
This normally occurs between an acid and a base. The role of the indicator is to detect the end point of the titration. When the endpoint is reached the indicator will change from its original color before the reaction.
Hence, the role of the indicator is to help us determine the endpoint of the reaction
