Question

Sulphur is soluble in
(A) Water
(B) Alcohol
(C) Carbon disulphide
(D) None of the above

Answer 1

We should be aware of dissolve like rules with respect to which this question can be answered within no time. Water, alcohol and carbon disulphide are the solvents.

Complete step by step answer:
Firstly, let's know about dissolve-like rules. According to this rule, the substances are soluble in only those solvents which would have the same polarity.
Option A is water. Water is a universal solvent. It is known as a universal solvent because it has a high dielectric constant in comparison to any other solvents. Sulphur is non-polar in nature, so it dissolves only in non-polar solvent. Water is a polar solvent. Sulphur is very difficult to dissolve in water as they both don't possess the same polarity. With reference to dissolve like a rule the sulphur is insoluble in water. Thus, option A is the wrong answer.
Option B is alcohol. Alcohol is a polar solvent. With reference to dissolves like rule non-polar sulphur does not dissolve in polar solvent that is alcohol. Therefore, option B is the wrong answer.
Option C is carbon disulphide. Carbon disulphide is a non-polar solvent. We know sulphur and most of its compounds are nonpolar. According to like dissolve like rule, sulphur is soluble in carbon disulphide. Thus, option C is the correct answer.
Since option C is the correct answer, Option D is also the wrong answer.

Thus, option C is the correct answer.

Note: Among the options given sulphur is soluble is carbon disulphide. Dissolving sulphur in carbon disulphide is very simple but it with extreme care as carbon disulphide is hazardous, flammable and chemically very toxic. It is soluble in benzene and toluene too. So, dissolving in benzene and toluene is a better option.
