Answer :
The option that describes a situation in which reduction occurs is Cl₂ becoming Cl⁻
In chemistry, reduction means a class of chemical reactions in which the number of electrons associated with an atom or group is increased.
A compound that accepts electrons is said to be reduced.
Situations in which reduction occurs include:
Cl₂ ⇒Cl⁻
When reduction occurs, the oxidation number (superindex) appears to decrease that number. In this case 2+ becomes 1-.
Note:
As with other problems, a decreasing oxidation number means that the compound or element is being reduced (gaining electrons), while an increasing oxidation number means it is being oxidized (losing electrons). increase.
