Question

Mn ion + H2O2 + H ion react to give Mn2+ ion + H2O

So2 + Br2 + H2O react to give So ion + H ion + Bromide ion

1) provide the half equation and give the oxidation and reduction

Answer 1

Half reactions are:

Mn⁺ $\rightarrow$ Mn²⁺ + e^-

H₂O₂+ 2H⁺ +2e^- $\rightarrow$ 2H₂O

SO₂ +2H₂O$\rightarrow$ SO₄^2-+4H⁺ +2e^-

Br₂ +2e^- $\rightarrow$ 2Br^-
