Consider a titration of a Mn2+ solution with EDTA. The
titration is performed at pH 10.0, where the alpha fraction for Y4-
is 0.355. For the MnY2- complex, Kf = 6.2 x 1013.
Calculate the conditional formation constant for MnY2-
(K­’MnY).
Find the concentration of free Mn2+, [Mn2+], in a
solution of 5.50 x 10-4 M MnY2-.
Calculate pNi at the equivalence point of a titration of
50.00 ml of 1.75 x 10-3 M Ni2+ by a 1.75 x 10-3 M EDTA
solution. Both solutions are buffered to a pH of 10.0, where
the alpha fraction for Y4- is 0.355. For the NiY2- complex,
Kf = 4.2 x 1018.
Calculate the concentration (M) of 50.00 mL of an
unknown solution of Mg2+ if 45.00 mL of 0.0100 M EDTA is required
to reach the end point.
