QUESTION:

5 Ethylenediaminetetraacetic acid abstracts bismuth(IIl) from its thiourea complex:Bi(tu)/' + H,Y'- ---> BiY- + 6tu + 2H+where tu is the thiourea molecule (NHz),CS. Predict the shape of a photometrictitration curve based on this process, given that the Bi(III) or thiourea complexis the only species in the system that absorbs light at 465 nm, the wavelengthselected for the analysis.

ANSWER:

Step 1 of 3

Titration is mainly an analytical method that gets used to analyse the concentration or quantity of any given analyte by using a known concentration of a particular titrant that gets reacted with that analyte through a stoichiometric manner.

Given data:

The wavelength is 465 nm.
