Separate this redox reaction into its balanced component half-reactions.

Question

Question:

Separate this redox reaction into its balanced component half-reactions.

Answer & Explanation:

The question says that we Separate the below redox reaction into its balanced component half-reactions: Cl2+2Na→2NaCl
Redox Reactions:
Oxidation-reduction reactions, also known as redox reactions, are common reactions that occur in nature. In these reactions, electrons are transferred from one chemical substance in the reaction to another chemical substance. The substance that undergoes oxidation will lose the electron, while the substance that undergoes reduction will gain the electron.
Answer and Explanation:
The two half-reactions are
Cl2+2e−→2Cl−
and
2Na→2Na++2e−
When splitting this reaction, you also need to show the sodium and chlorine as ions instead of an ionic complex for the half reactions to balance. When balancing half reactions, the charges on each side of the arrow need to equal each other. So, you can add electrons to balance the charge. This also will show you what is being oxidized and reduced. Notice that the chlorine is gaining electrons, so it is being reduced. Sodium is losing electrons, so it is oxidized.
