Introduction:
The equivalent weight is a term used in stoichiometry to represent the mass of a substance required to react with one mole of another substance. It is calculated based on the concept of equivalent proportions, where the number of equivalents of a substance is equal to its molar mass divided by its change in oxidation number.

Determination of the Equivalent Weight of Sulphur:
To determine the equivalent weight of sulphur, we need to consider its oxidation number. The oxidation number of sulphur is typically -2 in most compounds, such as sulfides (e.g., H2S) and sulfates (e.g., Na2SO4). However, there are also compounds where sulphur exhibits other oxidation states, such as +4 in sulfur dioxide (SO2) and +6 in sulfuric acid (H2SO4).

Calculating the Equivalent Weight:
To calculate the equivalent weight of sulphur, we follow these steps:

1. Determine the change in oxidation number:
In compounds where sulphur has an oxidation number of -2, its change in oxidation number is 0 when it remains in this state. Therefore, the change in oxidation number is 0 for most common sulphur compounds.

2. Calculate the molar mass of sulphur:
The molar mass of sulphur is 32 g/mol. This value is obtained from the periodic table, which lists the atomic mass of sulphur as approximately 32 atomic mass units (amu).

3. Determine the number of equivalents:
The number of equivalents is calculated by dividing the molar mass of sulphur by the change in oxidation number. Since the change in oxidation number is 0, the number of equivalents is equal to the molar mass of sulphur.

4. Express the equivalent weight:
The equivalent weight of sulphur is 32 g/equivalent.

Answer:
Based on the above calculations, the equivalent weight of sulphur is 32 g. Therefore, the correct option is 2) 32.

Summary:
The equivalent weight of sulphur is calculated by considering its oxidation number and molar mass. In most common sulphur compounds, the oxidation number of sulphur is -2, resulting in a change in oxidation number of 0. Therefore, the equivalent weight of sulphur is equal to its molar mass of 32 g/mol.
