In the reaction of oxalate with permannganate in acidic medium, the number of electrons involved in producing one molecule of is:
10
2
1
5
Balancing of Redox Reactions -
Oxidation number method
- wherein
1. Write the correct formula for each reactant and product.
2. Identify atom whose oxidation number is changed.
3. Calculate increase / decrease in oxidation number per atom and for the entire molecule / ion in which it occures.
4. Add on appropriate side so that the total ionic charges of reactants and products are equal.
5. Make numbers of hydrogen atoms in the expression on the two sides equal by adding to reactant or product
As we have learned ,
When oxalate reacts with permanganate in acidic medium.
We know that 10 e- transfer for 10 molecules of CO2 . So per molecule of CO2 transfer of e- is '1' .
10
