Tin(II) Reduction to Tin(IV)

Sn2+ + 2Fe3+ → Sn4+ + 2Fe2+

概要

Tin(II) ions reduce iron(III) to iron(II) while being oxidized to tin(IV). Stannous chloride (SnCl₂) is a widely used reducing agent in analytical chemistry. This redox reaction is used to pre-reduce iron(III) before titration with permanganate or dichromate.
