Question

What is the balanced net ionic equation for the reaction below in acidic solution? Enter the coefficient for each substance. Do not leave any answer box blank. Enter 1 if appropriate, or 0 (zero) if the substance does not appear on that side of the equation.
Mn2+ + BiO31- + H1+ + H2O
Bi3+ + MnO41- + H1+ + H2O

Answer 1

(Mn2+ + 4 H2O >> MnO4- + 8H+ + 5e-) x 2

(BiO3- + 6H+ + 2e->> Bi3+ + 3H2O) x 5

2Mn2+ + + 5BiO3- +14 H+ >> 2MnO4- + +5Bi3+ +7H2O

Answer 2

Your nomenclature leaves something to be desired, but here goes:
The usual reaction is that permaganate (MnO4-1) oxidizes something while the Mn+7 oxidation state is reduced, in this case, to the Mn+2 state. Thus, we would expect that Bi+3 is oxidized to the Bi+5 state in BiO3-.

We do the half-reactions, using water to and hydrogen ion to balance H and O requirements.

For the permangate-Mn+2 reaction:
MnO4- + 8H+ 5e -> Mn+2 + 4H2O and for the other reaction:
Bi+3 + 3H2O -> BiO3- + 6H+ + 2e.
We multiply the first reaction by 2 and the second by 5, and add to get:
2MnO4- + 5 Bi+3 + 7 H2O -> 2Mn+2 + 5 BiO3- + 14 H+

Answer 3

i desire you advise the a million/2-reaction technique, for the reason this is the best thank you to stability redox reactions. C2O4^2- + MnO4^- --> CO2 + Mn2+ 2(8H+ + MnO4^- + 5e- --> Mn2+ + 4H2O) 5(C2O4^2- --> 2CO2 + 2e-) ------------------------- ------------------------------ 16H+ + 2MnO4^- + 5C2O4^2- --> 2Mn2+ + 10CO2(g) + 8H2O
