Expert Solution

Oleic acid is an organic fatty acid. (C18H34O2)

It has the formula CH3(CH2)7CH=CH(CH2)7COOH. At room temperature oleic acid is in liquid state. It is colourless, odourless oil having boling point 360 °c.

As oleic acid is liquid at room temperature, we can not purified impure sample of oleic acid by recrystallization process. Because Crystallization process and recrystallization process are used for state substances.

To purified impure oleic acid we can use a distillation process.

Note:-

Crystallization:- The process of obtaining a solid in pure and crystalline form, from its solution is known as crystallizatio.

Recrystallization:- The process of repeated crystallization is known as recrystallization.

Distillation:- The process in which liquid is converted into its vapour phase at its boiling point and the vapour is then condensed back to liquid on cooling is known as distillation.

Distillation involves both evaporation of a liquid and condensation of its vapour.

You are attempting a recrystallization of the world’s only sample of charliebionic acid with a small amount of an unknown impurity.   The acid is not soluble at all in water. The acid is very soluble in hot ethanol but only slightly soluble at room temperature. But as the solution cooled to room temperature, no precipitate formed. However, when the solution was cooled in an ice bath solid immediately formed. This solid was dried and the melting point measured. The melting...
