Questions & Step-by-Step Solutions

What is the role of indicators in titration for qualitative analysis?
  • Step 1: Understand what titration is - it's a method used to determine the concentration of a solution.
  • Step 2: Know that an indicator is a substance that changes color at a certain pH level.
  • Step 3: During titration, you slowly add one solution to another until the reaction is complete.
  • Step 4: The endpoint of the titration is the point where the reaction is complete.
  • Step 5: The indicator changes color at the endpoint, signaling that the reaction is done.
  • Step 6: This color change helps you know when to stop adding the solution.
