Assign oxidation number to the underlined elements in each of the following species:
H₂S₂O₇

Question

Assign oxidation number to the underlined elements in each of the following species: H 2 S 2 O 7

Philoid · Accepted Answer

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

We know that,

O.N. of H = + 1

O.N. of O = -2

Therefore, we have,

2(+ 1) + 2(x) + 7(-2) = 0

2x = 12

X = + 6

The O.N. of S is + 6.
