Question

Name a substances that will reduce aqueous Iron(III)ions to Iron(II)ions

Answer 1

Ferric ions in solution can be reduced to ferrous ions by using hydrogen sulphide.

H2S + Fe3+(aq) →Fe2+(aq) + 2H+(aq) + S(s)

Answer 2

Answer: A substances that will reduce aqueous Iron(III) ions to Iron(II) ions is the zinc powder.

Explanation:

The presence of iron(II) ions or Fe2+ ions are identified by the formation of the green precipitate with sodium hydroxide solution (NaOH).

The equation of converting iron(III) ions to iron(II) ions is

Fe3+ + e- ---> Fe2+

It is a reduction.
