Question

balance the redox reaction mno4- +FeC2O4 gives Fe3+ +mn2+ +2CO2

Answer 1

Answer:

MnO4- ---------->Mn+2

MnO4- ---------->Mn+2+4H2O

MnO4-+8H --------->Mn+2 +4H2O

2[Mno4-+8H+5e- -------->Mn+2+4H2O]

2MnO4-+16H +10e- ------->2Mn+2+8H2O

...................................................................................

C2o4^_2---------->Co2

C2o4---------->2Co2

[C2o4^_2-------->2Co2+2e-]×5

5C2o4^_2-------->10Co2 +10e-
