At each temperature there are two compositions, say c 1 and c′ 2 one representing the composition of phenol in water (c 1, c 2 etc.) and the other in a solution of water in phenol (c′ 1, c′ 2 etc.). These solutions shown by c 1 and c′ 1, c 2 and c′ 2 etc. are called conjugate solutions.

WebExperiment: 1. Aim: To determine the Critical Solution Temperature (CST) or upper consolute point of phenol-water system.. Principle: Two partially miscible liquids may become completely miscible at a higher temperature since solubility increases with temperature generally. This miscibility temperature is different for different compositions … Web(insoluble in water) in phenol raises the upper CST of phenol-water system by about 300. Substances which are soluble in both the liquids tend to lower the upper CST and raise the lower CST. For example, sodium oleate is soluble in both water and phenol. Addition of 1% solution of sodium oleate to phenol-water system lowers the CST value by 450.
