Consider the titration of 40.0 mL of 0.0400 M mercaptoacetic acid (HSCH2CO2H, pKa1 = 3.64, pKa2 = 10.61) titrated with 0.100 M NaOH. a) Ve1 = mL b) The concentrations of the monoprotic and fully deprotonated forms are equal at Vp = mL c) Calculate the pH when 12.0 mL of titrant is added. (ANSWER FORMAT: If for example, the answer is 7.12, then c = 7, m =12) C = m =
