question 49

Multiple Choice

One source of iodine is sodium iodate. Iodine is produced by a series of reactions. The first reaction is a reduction reaction with sodium hydrogen sulfite. IO₃^-( aq) + 3 HSO₃^- (aq) → I^- (aq) + 3 SO₄^2- (aq) + 3 H⁺(aq)
5 I^- (aq) + IO₃^- (aq) + 6 H⁺ (aq) → 3 I₂(s) + 3 H₂O
