Question

Write balanced half-equations and combine the balanced half-equations to give the overall equation.
I⁻ + IO₃⁻ ⇒ I₂

Answer 1

Answer:

this is your answer

Explanation:

The oxidation half reaction is Fe

2+

(aq)→Fe

3+

(aq)+e

−

.

The reduction half reaction is H

2

O

2

(aq)+2H

+

(aq)+2e

−

→2H

2

O(l).

In the above half-reactions, all the atoms are balanced.

The oxidation half-reaction is multiplied by 2 so as to balance the number of electrons in oxidation half-reaction with reduction half-reaction.

2Fe

2+

(aq)→2Fe

3+

(aq)+2e

−

.

The oxidation half-reaction is then added to the reduction half-reaction to obtain a balanced chemical equation.
