Write a balanced half-reaction describing the reduction of gaseous dioxygen to aqueous oxide anions.

maksim [4K]

Answer: The balanced half reaction is written below.

Explanation:

Reduction reaction is defined as the chemical reaction in which an atom gains electrons. The oxidation number of the atom gets reduced during this reaction.

$X^{n+}+ne^-\rightarrow X$

When oxygen gas is reduced to oxide ions, the number of electron transferred are 2

The chemical equation for the reduction of oxygen gas to oxide ions follows:

$O_2+2e^-\rightarrow 2O^{2-}$

Hence, the balanced half reaction is written above.
