Question
The property exhibited by concentrated sulphuric acid when it is used to prepare hydrogen chloride gas from potassium chloride is ______.
Options
Dehydrating property
Drying property
Oxidising property
Non-volatile acid property
Solution
The property exhibited by concentrated sulphuric acid when it is used to prepare hydrogen chloride gas from potassium chloride is non-volatile acid property.
Explanation:
The volatile acid HCl is removed from its salt solution through a reaction between H2SO4 and NaCl.
