EDTA extracts bismuth(III) from the bismuth(III)-thiourea (Bi(tu) 3 +) complex according to the reaction, Bi(tu) ++ H₂Y²- → BiY6 tu+ 2H+ where H₂Y²- represents the deprotonated form of EDTA. The Bi(tu)3 + complex exhibits an absorption maximum at 470 nm, whereas the bismuth (III)-EDTA (BIY) complex exhibits an absorption maximum at 265 nm. Which of the spectrophotometric titration curves ヒヒ Volume of titrant Volume of titrant LL Volume of titrant B D represent the titration of Bi(tu)3 + with EDTA when the Volume of titrant absorbance is measured at 470 nm? A F E D B Which of the spectrophotometric titration curves represent the titration of Bi(tu)3 + with EDTA if the absorbance was instead measured at 265 nm? F A B D E Absorbance E Volume of titrant Volume of titrant F
