Question

What is the oxidation number of carbon in k2c2o4?

Answer 1

⭐Hey

oxidation no. ==}. +1

Answer 2

Explanation:

Potassium is a monovalent atom, so one potassium atom will have a charge of +1. Therefore, two potassium atoms will have a charge of +2.

Also, oxygen has a charge of -2. So, four oxygen atoms will have a charge of -2 × 4 = 8.

Therefore, let the oxidation state of one carbon is x.

Calculate the oxidation number of carbon atom in $K_{2}C_{2}O_{4}$ as follows.

                      2 + 2x - 8 = 0

                             2x = +6

                               x = +3

Therefore, oxidation state of carbon is +3.
