Critical solution temperature (or the con-solute temperature) for partially miscible liquids (e.g., phenol-water) is the minimum temperature at which___________________?
Correct answer: C. A homogeneous solution (say of phenol water) is formed
- A. Two liquids are completely separated into two layers
- B. Mutual solubility of the two liquids shows a decreasing trend
- C. A homogeneous solution (say of phenol water) is formed
- D. None of these
Explanation
At the upper critical solution temperature, the two partially miscible liquids become completely miscible and form one homogeneous phase. Below this temperature, compositions can separate into two liquid layers.
