Cst of phenol water system
Webchloride raises the upper CST of phenol-water system by 12". About 0.12 molar solution of naphthalene (insoluble in water) in phenol raises the upper CST of phenol-water … WebA pair of liquids is considered partially miscible if there is a set of compositions over which the liquids will form a two-phase liquid system. Liquids are never actually completely immiscible. To take an extreme case, liquid mercury, when equilibrated with water, has some H 2 O dissolved in it, and some mercury dissolves in the water ...
