Recrystallization: Dissolve your solid and precipitate your crystals

About this Simulation

This mini-simulation is part of the larger “Recrystallization: Purify your solid.” See the full version for more information.

How are impure colored substances turned into pure white or transparent crystals?

In this simulation, you will learn what are the steps to follow in order to dissolve a solid and recrystallize it to eliminate impurities. You will learn why it is important to choose the right solvent and which are the best ways to recrystallize your solid.

Dissolve and recrystallize

Analyze your solid, decide on the right solvent to use, and carry out the entire process -- from dissolving your solid when the solvent is boiling hot, to cooling it down gradually by using an ice bath.

Recrystallization in no time!

Recrystallization is a process that takes time since we need to wait long periods for our solvent to heat up, our mixture to cool, and our crystals to form. Thanks to this virtual simulation, we can offer this experience in a much shorter time frame, minimizing the waiting times!

From the big picture to individual tasks

Get an overview of how recrystallization works and then follow the step by step lab protocol. You will not only understand how this technique is used, but also all the steps that need to be completed to ensure a successful recrystallization.
