Answer 1

$\mathfrak{\blue{\underline{\underline{Question}}}}$

Oxidation number of S in ${S{O}_{3}}^{2-}$

$\mathfrak{\blue{\underline{\underline{Answer}}}}$

Oxidation Number: The charge present in an atom when it is present in combined state with atom of another element.

Oxidation number of ${S{O}_{3}}^{2-}$

Let the Oxidation number of S be x

We know,

Oxidation number of O = -2

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

x - 6 = -2

x = -2 + 6

x = +4

Answer:

$\boxed{+4}$
