Iodine, i2, has many uses, including the production of dyes, antiseptics, photographic film, pharmaceuticals, and medicinal soaps. it forms when chlorine, cl2, reacts with iodide ions in a sodium iodide solution. which of the following half-reactions for this oxidation‑reduction reaction describes the oxidation, and which one describes the reduction? cl2 + 2e‒ → 2cl‒ 2i‒ → i2 + 2e‒

Explanation:

Oxidation-reduction reaction is the simulaneous oxidation and reduction of the substances and is represented by two half-reactions.

The oxidation half-reaction is the loss of electrons, with the consequent increase in the oxidation state by the oxidized substance.

In this case, the process that shows the loss of electrons is:

That reaction shows:

On the other hand, the reduction half-reaction is the gain of electrons, with the consequent reduction of the oxidation state by the reduced substance.

In this case, the process that shows the gain of electrons is:

That reaction shows:

Summary:

water and alcohols have similar properties because water molecules contain hydroxyl groups that can form hydrogen bonds with other water molecules and with alcohol molecules, and likewise alcohol molecules can form hydrogen bonds with other alcohol molecules as well as with water.
