Using the set of smallest whole number coefficients to balance
the redox equation
MnO4- + NO2- --->
MnO2 + NO3-
in basic solution, you get
a) 2 OH- on the right.
b) 3 OH- on the left.
c) 1 H2O on the right
d) 3 H2O on the left
When the following oxidation–reduction reaction is balanced with
lowest whole-number coefficients, what is the coefficient for
Mn2+(aq)?
__MnO4–(aq) + __C2H5CHO(aq) + __H+ (aq) → __Mn2+(aq) +
__C2H5COOH(aq) +__ H2O(l)
When I balanced this equation I got the following:
1MnO4–(aq) + 1C2H5CHO(aq) + 6H+ (aq) → 1Mn2+(aq) + 1C2H5COOH(aq)
+3 H2O(l)
so therefore, the answer would be 1. However, the answer is 2.
Can someone explain why the answer is 2 and what I did wrong?
When the following oxidation-reduction reaction in acidic
