Three drops of the phenolphthalein chemical indicator should be added to the acidic analyte sample (KHP or citric acid) before every titration. You will then carefully add the base to the analyte until the solution turns O a. from clear to a very pale pink color. O b. from a pale pink color to totally clear. O. from a dark pink color to totally clear. O d. from clear to a very dark pink color.
