Questions & Step-by-Step Solutions

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.
