Iron(III) is best determined by addition of excess EDTA, followed by back-titration with a metal ion that reacts rapidly with EDTA. A 700.0-mg sample is dissolved, 20.00 mL of 0.0500M EDTA is added, and the excess EDTA is titrated with 5.08 mL of 0.0420M copper(lI). Calculate the percentage of Fe,O, in the sample.
