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
Updated On: Apr 1, 2025
- Hydrogen chloride gas
- Chlorine gas
- Sulphur dioxide gas
- Hydrogen gas
Hide Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
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.
