Assign oxidation number to the underlined elements in each of the following species:
CaO₂

Question

Assign oxidation number to the underlined elements in each of the following species: Ca O 2

Philoid · Accepted Answer

Let the oxidation number(O.N.) of O be ‘x’

We know that,

O.N. of Ca = + 1

Therefore, we have,

(+2) + 2(x) = 0

X = -1

The O.N. of O is -1.
