Critical solution temperature (or the con-solute temperature) for partially miscible liquids (e.g., phenol-water) is the minimum temperature at which

mutual solubility of the two liquids shows a decreasing trend.

a homogeneous solution (say of phenol water) is formed.

two liquids are completely separated into two layers.
