Question

What can we say about reduction and oxidation in terms of oxidation number?

Answer 1

In a redox reaction, the element that loses electrons is oxidized and will have an increase in its oxidation number, while the element that gains electrons is reduced and will have a decrease in its oxidation number.

Step-by-step explanation:

In a redox reaction, the element that loses electrons is oxidized and will have an increase in its oxidation number.
