Question

Solve the problem

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
conneril) Calculate the percentage of Fe,0, in the sample.
A 377.0-mg sample of As,0, is dissolved to give two molecules of H,AsO, per one
molecule of As,0, and is oxidized to H,AsO, with 31.48 mL of 0.0502M (0.1040N)
iodine (1,) Calculate the percentage of As,O, (form wt = 197.84) in the sample.
