Question

If a mixture of $LiCl$ and $NaCl$ is melted and cooled :

• A. a solid solution is formed
• B. mixture formed is called eutectic mixture
• C. $Ti{O}_{1.8}$ is non-stochiometric solid solution of $T{i}_2{O}_3$ and $Ti{O}_2$
• D. neither $LiCl$ nor $NaCl$ separates

Answer 1

Answer: (A), (B), (C), (D)

The correct options are
A a solid solution is formed
B mixture formed is called eutectic mixture
C $Ti{O}_{1.8}$ is non-stochiometric solid solution of $T{i}_2{O}_3$ and $Ti{O}_2$
D neither $LiCl$ nor $NaCl$ separates

If a mixture of $LiCl$ and $NaCl$ is melted and then cooled, the following happens.
(A) A solid solution is formed.
(B) Mixture formed is called eutectic mixture.
A mixture of two or more substances which melts at the lowest freezing point of any mixture of the components is called eutectic mixture. This temperature is the eutectic point.
The liquid melts has the same composition as the solid.
(C) $Ti{O}_{1.8}$ is non-stochiometric solid solution of $T{i}_2{O}_3$ and $Ti{O}_2$.
(D) Neither $LiCl$ nor $NaCl$ seperates as the liquid melt has the same composition as the solid.
