Question

This is the question I need help with. I would really love to understand how reduction occurs here. Thanks in advance for helping me understand this.Which option describes a situation in which reduction occurs?Cl2 becoming Cl–Cl, 2, becoming Cl, –Xe2+ becoming Xe6+Xe, 2+, becoming Xe, 6+Al becoming Al3+Al becoming Al, 3+S2– becoming S

Answer 1

In chemistry, reduction means any of a class of chemical reactions in which the number of electrons associated with an atom or a group of atoms is increased.

You can say that a compound that is gaining electrons is being reduced.

The situation where the reduction is occurring is:

$Cl^2\to Cl^-,$

When the reduction occurs, the oxidation number (which is the superindex), it seems that is reducing this number. In this case, 2+ become 1-.

Remember: when the oxidation number is reducing, it means that the compound or element is a reduction (gaining electrons) and when the oxidation number is increasing, it means that it is oxidation (losing electrons) such as the other cases of the problem.
