Ethylenediaminetetraacetic acid displaces bismuth( III) from its thiourea complex: Bi(tu)63+ + H2Y2- ( BiY- + 6tu +
Question:
Bi(tu)63+ + H2Y2- ( BiY- + 6tu + 2H+
Where tu is the thiourea molecule, (NH2)2CS. Predict the shape of a photometric titration curve based on this process, given that the Bi(III)/thiourea complex is the only species in the system that absorbs at 465 nm, the wavelength selected for the titration.
