Iron (III) ions form a deep-coloured complex with a maximum absorption at about 525nm; this complex is used as the basis for the photometric titration of iron(III) ion with standard EDTA solution.

How many moles of Ca and Fe respectively could EDTA chelate?
1 mole of EDTA will chelate with 1 mole of Ca2+ ions or 1 mole of Fe2+ or Fe3+ ions.
Role of phosphoric acid in dichrometry titration?
The phphoric acid is used to form stable complexes with Fe3+ ion
Which is most likely to be reduced Fe2 Cu2 Fe3 or Zn2?
Answer this question… Fe3+
What is the purpose of adding sulfuric acid to iron samples before titration?
Depends on the method used. In general, it helps to dissolve all the sample. But in case of using manganometry in the determination, then the acid is needed to ensure low pH, because the reaction Fe2+ + MnO4- = Fe3+ + Mn2+ proceeds only in high pH. If the pH was neutral or basic, solid MnO2 would be created, which is not favorable (we need to know prpreciselyow many mno4- oxidates one fe2+).
What is the chemical formula for Fe3 combined with S2?
The chemical formula for Fe3 combined with S2 is Fe2S3.
