Explain the concept of reduction/oxidation states in a chemical reaction.

•The increase in the oxidation state of an atom as a result of a chemical reaction is called oxidation and involves the loss of electrons. A decrease in the oxidation state of an atom is called a decrease and includes an electron gain.

•Oxidation is the loss of electrons or an increase in the oxidation state of certain atoms, ions, or atoms in a molecule. Reduction is the addition of electrons or a decrease in the oxidation state of certain atoms, ions, or atoms in a molecule (reducing the amount of oxidation).

Hope this helps
