Question

Balance the following redox reactions by half reaction methods step by step
1. Cr(OH)3 +IO3^- → I^- +CrO4^2- (In basic medium)
2. MnO4^- +SO3^-→ Mn^2+ +SO4 ^2- (In acidic medium)
3. Br2 +H2O2 → BrO3^- + H2O (In acidic medium)

Answer 1

Answer:

I am not a chemistry student so I don't know this answer

Answer 2

Answer:

1)Cr(OH)3 +IO3^- → 3I^- +CrO4^2.

2)MnO4^- +SO3^-→ Mn^2+ +3SO4 ^2.

3)Br2 +H2O2 → BrO3^- + 2H2O.
