Question

what is oxidation number change method?​

Answer 1

Answer:

By oxidation number change method. In the oxidation number change method the underlying principle is that the gain in the oxidation number (number of electrons) in one reactant must be equal to the loss in the oxidation number of the other reactant.

Answer 2

Some points on oxidation number change method are as follows:-

1. This method was Given by Johnson.

2. But this term was first used by Antoine Levoisier.

3. According to this method in a balanced redox reaction, total increase in oxidation number must be equal to total decreased oxidation number.

4. This equivalence provides the basis for balancing redox reactions.

5. It is applicable on fully ionic elements only.

6. Oxidation state of all the pure elements is going to be zero all the time.
