Which of the following oxoacids of sulphur contains \(S\) in two different oxidation states?
\(H_2S_2O_3\)
\(H_2S_2O_6\)
\(H_2S_2O_7\)
\(H_2S_2O_8\)
The Correct Option is A
Solution and Explanation
In \(H_2S_2O_3\), sulphur exhibits two different oxidation states +6 and –2.
So, the correct answer is (A) : \(H_2S_2O_3\)

Concepts Used:
Sulphur
Sulphur is a non-metal that is tasteless, abundant, and odorless. Sulphur is a yellow crystalline compound, in its natural form. In surroundings, it can be observed as a loose element or in the form of sulfide and sulfate minerals. Sulphur is commonly known for its foul odor, which is sometimes compared to rotten eggs, that odor is actually caused by hydrogen sulfide (H2S).
Physical Properties:
- It appears yellow in color.
- It is insoluble in water. But, it is much soluble in toluene (methylbenzene) and carbon disulfide.
- It is defined as a poor conductor of electricity and heat because of its non-metallic property.
- Where we consolidate Sulphur vapor, we get a fine powder at that period of time that shapes a pattern resembling a flower. It is referred to as the 'Flower of Sulphur'.
Chemical Properties:
- Most of the metals and non-metals react with Sulphur, under specific conditions.
- Sulphur burns in excess of air with a bright blue fire and produces Sulphur IV oxide and some amount of Sulphur VI oxide.
- Sulphur is the compound that reacts with Hydrogen at very high temperatures and produces hydrogen sulphide.
- Sulphur vapor also reacts with hot coke to form a fluid, carbon disulfide.
