The oxidation state of single oxygen atom is -2
since it is more electronegative and like to gain electrons.
The sum of the oxidation states of each atom = charge of
compound
Let’s say the oxidation state of Sulfur is x.
Hence,
x +4 * (-2) = -2
x – 8 =
-2
x = +6
The
oxidation state of individual Sulfur atom is +6
