Recrystallization is the process in which a solid is dissolved in a suitable solvent, usually at elevated temperatures. as the solution is heated, it becomes saturated, and the unsaturated solid begins to reform crystals. recrystallization is a common way to purify a solid. the formation of the crystalline structure tends to dissolve impurities when re-grown slowly from a unsaturated solution, resulting in crystals with fewer impurities than the original crystals.

This was a completing question and what is shown is the answer (with a few errors).

The question for completion is:

Recrystallization is the process in which a solid is dissolved in a solvent, usually at   temperatures. as the solution , it becomes , and the solid begins to reform crystals. recrystallization is a common way to a solid. the formation of the crystalline structure tends to impurities when re-grown slowly from a solution, resulting in crystals with impurities than the original crystals.

And you are also given this bank of words from which to select the right words:

[ lack, is heated, elevated, lower, suitable, dissolve, excess, fewer, reject, more, cools, saturated, purify, unsaturated ]

Herewith, I show you the right

Recrystallization is the process in which a solid is dissolved in a (suitable) solvent, usually at  (elevated)  temperatures. as the solution (is heated), it becomes (saturated), and the (excess) solid begins to reform crystals. Recrystallization is a common way to (purify) a solid. The formation of the crystalline structure tends to (reject) impurities when re-grown slowly from a (saturated) solution, resulting in crystals with (fewer) impurities than the original crystals.

As you can see, I corrected some words from the statement posted because they did not fit with the recrystalization process.

Recristalization is indeed a technique to purify solids by dissolving them in an adequate solvent (remember polar dissolve polar and non-polar dissolve non-polar).

Then, you heat the solution and as the solvent evaporates the solutions gets more concentrated, when it is saturated the solute starst to precipitate in form of crystals which have fewer impurities.

Ok where is the image ?
