In the detection of II group acid radical, the salt containing chloride is treated with concentrated sulphuric acid, the colourless gas is liberated. The name of the gas is
- Hydrogen chloride gas
- Chlorine gas
- Sulphur dioxide gas
- Hydrogen gas
The Correct Option is A
Approach Solution - 1
1. Analyzing the Reaction:
In the detection of the II group acid radical (chlorides), when a salt containing chloride ions is treated with concentrated sulphuric acid, a colourless gas is liberated. This gas is hydrogen chloride (HCl) gas, which is characteristic of reactions involving chloride salts and concentrated sulphuric acid.
2. Identifying the Gas:
The reaction results in the release of hydrogen chloride gas (HCl), which is a colourless gas with a pungent odor. It is produced by the reaction of the chloride salt with concentrated sulfuric acid.
Final Answer:
The name of the gas is (A) "Hydrogen chloride gas."
Approach Solution -2
When a chloride salt is treated with concentrated sulfuric acid, hydrogen chloride gas (HCl) is liberated. This is a characteristic reaction for detecting II group acid radicals, where chloride ions react with sulfuric acid to release hydrogen chloride gas. The reaction involves the production of HCl as a colorless gas.
The correct answer is (A) : Hydrogen chloride gas.
