WitrynaIt is the distribution coefficient, whose value decides the mobility of substance S from phase 1 to phase 2. If the value of KD is sufficiently large, only then such a complete mobility or transfer of substance to phase 2 will take place. However, if this value is small, then the substance will remain in phase 1 only. WitrynaWhen an impure liquid is cooled to its melting point the liquid, undergoing a phase transition, crystallizes around the impurities and becomes a crystalline solid. If there are no impurities then the liquid is said to be pure and can be supercooled below its melting point without becoming a solid.
