Problem: You are titrating an acidic solution with a basic one, and just realized you forgot to add the indicator that tells you when the equivalence point is reached. In this titration, the indicator turns blue at the equivalence point from an initially colorless solution. You quickly grab a bottle of indicator and throw some into your titration beaker, and the whole solution turns dark blue.What do you do now?

Recall that in the titration of acid and base:

  • If the indicator is not added before the addition of base and after the addition of indicator is added to the solution and it turns blue, the solution is already in equivalence point.
