Questions and Answers

What is recrystallization?

A way to increase the solubility of a given solvent

A method of synthesizing organic substances in the laboratory

A technique for isolating impurities from plants

A method of purifying a solid (correct)

What are the two types of impurities in recrystallization?

Those that are completely insoluble in the solvent

Those that have the same solubility as the main component and those more soluble

Those more soluble in a given solvent than the main component and those less soluble (correct)

Those that have the same solubility as the main component and those less soluble

Why is it important to choose the right solvent in recrystallization?

Because some impurities have the same solubility as the main component (correct)

Because some solvents can increase the solubility of impurities

Because some solvents can decrease the solubility of the main component

Because some solvents can react with the main component

Flashcards

What is recrystallization?

A method of purifying a solid compound by dissolving it in a suitable solvent, then allowing it to crystallize out as the solution cools, leaving impurities behind.

What are soluble impurities in recrystallization?

Substances that dissolve more easily in the chosen solvent than the desired compound.

What are insoluble impurities in recrystallization?

Substances that don't dissolve as well in the chosen solvent as the desired compound.
