Question

Find the oxidation no. Of c in h2co3

Answer 1

Explanation:

Oxidation number is defined as the number holded by an atom by either gain or loss of electrons when it chemically combines with another atom.

In $H_{2}CO_{3}$ compound, the oxidation number of a hydrogen atom is +1  and oxidation number of an oxygen atom is -2.

Therefore, calculate the oxidation number of carbon atom in $H_{2}CO_{3}$ as follows.

                   2(1) + x + 3(-2) = 0            

(Total charge on the compound is zero because it is a neutral in nature.)

                 2 + x -6 = 0

                     x - 4 = 0

or,                 x = +4

Thus, we can conclude that oxidation number of C in $H_{2}CO_{3}$ is +4.
