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 add some to your titration beaker, and the whole solution turns dark blue. What do you do now?

Hi everyone here we have a question asking us to consider the following situation. A student was asked to titrate a weak acid with a strong base. The student then started slowly adding the strong base to a fixed amount of weak acid. However, he remembered that he didn't put in the indicator. The indicator was supposed to change from colorless to pink when the tight rations complete, The student then tried adding a prescribed amount of the indicator to the solution that they already started high trading. The solution did not change color and was still colorless. What should the student do next? So the solution did not change color and was still colorless, which means we have not reached the equivalence point yet. So we would need to keep adding and that is our answer. Thank you for watching. Bye.
