How can we identify which substance Ina reaction undergo oxidation and reduction

Answer 1

There are several ways to identify which substance undergoes oxidation and reduction in a reaction:

1. Look at the changes in oxidation states: The substance that increases its oxidation state is undergoing oxidation, while the substance that decreases its oxidation state is undergoing reduction.

2. Identify the exchange of electrons: The substance that loses electrons is being oxidized, while the substance that gains electrons is being reduced.

3. Check for changes in the number of oxygen atoms: If a substance gains oxygen atoms, it is being oxidized; if it loses oxygen atoms, it is being reduced.

4. Look for changes in the number of hydrogen atoms: If a substance loses hydrogen atoms, it is being oxidized; if it gains hydrogen atoms, it is being reduced.

By carefully analyzing these factors, one can identify which substance is undergoing oxidation and reduction in a chemical reaction.
