Compare the oxidation number of sulfur in the following molecules and ions: (F) SO2Cl2 (G) HSO3?

(F)
Oxidation number of O = -2
Oxidation number of Cl = -1

For the neutral compound SO₂Cl2, sum of oxidation numbers = 0
(Oxidation number of S) + (-2)×2 + (-1)×2 = 0
Oxidation number of S = +6

====
(G)
"HSO₃" does not exist. It should be "HSO₃⁻" instead.

Oxidation number of H = +1
Oxidation number of O = -2

For the HSO₃⁻ ion carrying 1 negative charge, sum of Oxidation numbers = -1
(+1) + (Oxidation number of S) + (-2)×3 = -1
Oxidation number of S = +4

(F) SO2Cl2 6+
(G) HSO3 5+
