Concept

Problem: Balance the following redox reactions occurring in basic solution.MnO4−(aq) + Br -(aq) → MnO2(s) + BrO3−(aq)a. MnO4−(aq) + H2O(l) + Br−(aq) → MnO2(s) + 2OH−(aq) + BrO3−(aq)b. 2MnO4−(aq) +  H2O(l) + Br−(aq) → 2MnO2(s) + 2OH−(aq) + BrO3−(aq)c. 2MnO4−(aq) +  H2O(l) + Br−(aq) → 2MnO2(s) + OH−(aq) + BrO3−(aq)d. MnO4−(aq) +  H2O(l) + 2Br−(aq) → MnO2(s) + OH−(aq) + 2BrO3−(aq)

Problem Details

Balance the following redox reactions occurring in basic solution.

MnO4(aq) + Br -(aq) → MnO2(s) + BrO3(aq)

a. MnO4(aq) + H2O(l) + Br(aq) → MnO2(s) + 2OH(aq) + BrO3(aq)

b. 2MnO4(aq) +  H2O(l) + Br(aq) → 2MnO2(s) + 2OH(aq) + BrO3(aq)

c. 2MnO4(aq) +  H2O(l) + Br(aq) → 2MnO2(s) + OH(aq) + BrO3(aq)

d. MnO4(aq) +  H2O(l) + 2Br(aq) → MnO2(s) + OH(aq) + 2BrO3(aq)
