Question

The azeotropic mixture of water (boiling point $={100}^o$C) and $HCl$ (boiling point $={85}^o$C ) boils at about ${110}^o$C. During distillation of this mixture, it is possible to obtain:

• A. pure $HCl$
• B. pure $H_{2}O$
• C. pure $HCl$ as well as $H_{2}O$
• D. neither pure $H_{2}O$ nor pure $HCl$

Answer 1

Answer: (D)

neither pure $H_{2}O$ nor pure $HCl$

Solution:- (D) neither pure $H_{2}O$ nor pure $HCl$

Azeotropic mixture is constant boiling mixture, it is not possible to separate the components of azeotropic mixture by boiling.
