If the solubilities of different components (in a liquid-liquid extraction system) increase with rise in temperature, then the temperature above which they dissolve completely is known as the critical solution temperature (CST or consolute temperature). If solubilities increase with decrease in temperature, then CST is the temperature below which they dissolve completely. If a binary system has no critical solution temperature, it implies that________?
AThe system comprises of an azeotrope
BThe system comprises of partially miscible liquids
CThe system comprises of miscible liquids
DOn heating, a vapor phase will appear; while on cooling, a solid phase will appear
Correct answer
D. On heating, a vapor phase will appear; while on cooling, a solid phase will appear
Explanation
The correct answer is On heating, a vapor phase will appear; while on cooling, a solid phase will appear.
