Which of the following should be done first if, during a titration using phenolphthalein as an indicator, a student adds more than the expected amount of solution from the buret and the solution still hasn't turned pink? Hint: Asking the TA should never be your first step when problem solving. Ask the TA to do the titration. Put water in the burette. Pour out all of your solutions and leave the lab with a failed experiment. Add acid to the flask and continue the titration. Add a drop of phenolphthalein indicator to the solution to see if it turns pink.
