when setting up their experiment, a student discovered that the solution in their flask turned bright pink upon adding 2 drops of the indicator, even before beginning the titration. what do you suspect was the mistake that the student made?

    I don't know the experiment you are doing but it's probably a titration experiment. The indicator turning pink (assume the indicator was phenolphthalein) means there was base in the flask at the beginning.
