1. Manganese(II) (Mn2+) forms a complex with EDTAaccording to Mn2+ + Y4- <->MnY2- with a formation constant Kf = 7.8 x1013.
(a) 23.14 mL of 0.07893 M Mn2+ was titrated with0.08130 M EDTA at pH 10.00. Calculate the endpoint volume for thetitration.
(b) Calculate the conditional formation constant(Kf’) for Mn2+ at pH 10.00 whereaY4- = 0.30.
(c) Calculate the concentration of free Mn2+ insolution at the endpoint of the titration at pH 10.00.
(d) Calculate the concentration of free Mn2+ insolution following the addition of 15.00 mL of 0.08130 M EDTA at pH10.00.
(e) Calculate the concentration of free Mn2+ insolution following the addition of 25.00 mL of 0.08130 M EDTA at pH10.00.
