Full acid, HOOC = CH-COOH is a biphatic acid and we will label it as H2M.
Acid constant data for the two protonation phases of the acid:
K H.M+H2O = H, 0++HM- HM +H2O = H, 0++M2– a1 = 1.3x10-2 K.2 = 5.9 x 10-7
Measure 0.1 ml of 0.100 M of malic acid with 0.100M NaOH and measure the H variability as a function of the added base volume.
A. Calculate the PH value at the beginning of the titration.
B. Calculate the pH value at the first equivalent point.
C. Calculate the pH value at the second equivalent point.
D. Draw the titration curve in the graph. Indicate in the graph titles and units for the axes.
