Short Answer
Consider the titration of 25.0 mL of an 0.11 M lactic acid solution CH3CH(OH)COOH (Ka= 8.4 x10-4) with 0.150 M NaOH.a) Calculate the pH after 10 mL of the NaOH solution has been added.b) Calculate the pH of the solution at 10 mL of NaOH past the stoichiometric point.c) Would phenol red (pKin = 7.9) or phenolphthalein (pKin = 9.4) be a better indicator for this titration?
