Equivalent weight of Br₂ is 96 in the following disproportionation reaction: Br₂ + OH⁻ Br⁻ + H₂O + ? (oxidized product). The oxidation state of Br in the oxidized product is (Br = 80)
Answer:
5.00
Solution:
Balanced: 3Br₂ + 6OH⁻ 5Br⁻ + BrO₃⁻ + 3H₂O. Per 3 mol Br₂, 5e⁻ are transferred (5 Br atoms gain 1e each, 1 Br loses 5e). E = 3 × 160/5 = 96, matching the given value. The oxidized product is BrO₃⁻ with Br in +5. Ans: 5.
