For the redox reaction
the correct coefficients of the reactants for the balanced equation are
2 | 16 | 5 |
2 | 5 | 16 |
16 | 5 | 2 |
5 | 16 | 2 |
As we learnt
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
