Question

In polythionic acid, H S O (x = 3 to 5) the oxidation state(s) of sulphur is/are: 2 x 6

(A) + 5 only
(B) + 6 only
(C) + 3 and + 5 only
(D) 0 and + 5 only

Prashant Kotian · Accepted Answer

Correct answer: D) 0 AND + 5 ONLY. The general structure of polythionic acids is – Here n = 1 to 3. Thus, possible oxidation states of sulphur are 0 and +5 only.
