The Difference Between a Pure Substance and an Impure Substance?

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.

Witryna8 lis 2024 · By “pure”, we simply mean that only one chemical substance is present in the sample. So, water has a definite phase, but mixtures do not. This is partly a disclaimer so that questions such as "is glass a liquid or a solid?" 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.
