Question

Azeotropic mixture of HCl and H₂O has ______.

Options

• 48% HCl

• 22.2% HCl

• 36% HCl

• 20.2% HCl

Answer 1

Azeotropic mixture of HCl and H₂O has 20.2% HCl.

Explanation:

Hydrogen chloride (HCl) and water (H₂O) form an azeotropic mixture at 20.2% HCl by mass. This azeotrope boils at approximately 110°C and behaves as a constant boiling mixture. It cannot be separated by simple distillation into pure components. Thus, the azeotropic mixture of HCl and H₂O has 20.2% HCl and 79.8% water.
