Redox reaction
Posted: Sun Mar 31, 2019 10:15 am
Can somebody out here help me with this redox reaction? it says that KMnO4 reacts with K2C2O4 in acidic conditions and the products are MnO2 and CO2?
this is how I did it:
[KMnO4 + (4H+) + (3e-) -----> MnO2 + (K+) + 2H2O] *2
[K2C2O4 ------> 2CO2 + (2K+) + (2e-) ] *3

2KMnO4 + 3K2C2O4 + (8H+) ------> 2MnO2 + 6CO2 + (8K+) + 4H2O
this is how I did it:
[KMnO4 + (4H+) + (3e-) -----> MnO2 + (K+) + 2H2O] *2
[K2C2O4 ------> 2CO2 + (2K+) + (2e-) ] *3
