Recrystallization can best be described as a process in which - A solid is fully dissolved in solvent when heated, but it does not remain in solution after cooling - A solid is fully dissolved in a solvent at room temperature to create a solution - A solvent is evaporated using heat and/or reduced pressure to leave any dissolved solutes behind as solids - A solid is fully dissolved in a solvent when heated, but remains in solution even after cooling

Solutions

Solutions can be considered as homogeneous mixtures which contain two or more than two chemical substances. The chemical substance which is the greater part is defined as solvent. And the chemical substance that is dissolved in a solvent is referred to as solute. Solution chemistry plays an important role in chemistry since it supports many commercial applications of solutions.
