Roasting of Sulphides and the Formation of Gas X

Roasting of sulphides is a process that involves heating the sulphide ores in air. This process is commonly used in the extraction of metals such as zinc, lead and copper. During this process, the sulphide ores are converted into their respective oxides.

The gas X that is produced during the roasting of sulphides is a colourless gas with a choking smell of burnt sulphur. This gas is known to cause great damage to the respiratory organs due to acid rain. Some key properties of gas X are:

- It is acidic in nature
- Its aqueous solution is acidic
- It acts as a reducing agent
- Its acid has never been isolated

Identifying Gas X

Based on the properties of gas X, we can identify it as sulphur dioxide (SO2). Here are some reasons why:

- Sulphur dioxide is a colourless gas with a choking smell of burnt sulphur, which matches the description of gas X.
- Sulphur dioxide is known to cause respiratory damage due to acid rain, which is consistent with the information given in the question.
- Sulphur dioxide dissolves in water to form sulphurous acid, which is acidic in nature. This explains why the aqueous solution of gas X is also acidic.
- Sulphur dioxide is a reducing agent, which means that it can donate electrons to other substances. This property is consistent with the information given in the question.
- Sulphur dioxide does not have a well-defined acid, which explains why the acid of gas X has never been isolated.

Therefore, the correct answer to this question is option A, sulphur dioxide (SO2).
