Question #27168
half reactions

Mn 2+ + BiO3 --> MnO4- + Bi3+

im trying to work out the half reaction and redox of this equation
Expert's answer
Mn2+ + BiO3- --> MnO4- + Bi3+
Mn lose 5 electrons:
Mn2+ - 5e- = Mn+7O4-
Bi takes 3 electrons:
BiO3- + 3e- = Bi3+
So in this reaction, manganese is reductant and Bismuth is oxidant.
