Chemistry
1 answer:
Greeley [361]3 years ago
4 0

Answer:

Two

Explanation:

I believe your unbalanced equation should be

H₂O₂ + I₂ ⟶ IO₃⁻

The half-reactions and the overall reaction are:

5 × [H₂O₂ + 2H⁺ +2e⁻ ⟶ 2H₂O]

1 × <u>[ I₂ + 6H₂O ⟶ 2IO₃⁻ + 12H⁺ + 10e⁻] </u>

      5H₂O₂ + I₂ ⟶ 2IO₃⁻ + 2H⁺ + 4H₂O

The reaction needs two hydrogen ions for balancing.
