Molarity

Molarity is the concentration of a certain compound in a solution. More specifically, it is used to define the number of moles present in a liter of solution.

This program, aptly named Molarity, can help you understand this simple unit of measurement, as well as learn more about the solubility of certain products, through a very straightforward simulation.

You can get started easily enough by just selecting the generic drink mix and playing around with the solute amount and solution volume. If both are at 1, the molarity, or solution concentration, will also have a value of 1.

If you reduce the solute amount, the molarity will decrease, while decreasing the solution volume will increase the molarity. It is worth keeping in mind that molarity can be limited by solubility.

There are a few other solutes you can work with, such as Gold chloride and Potassium permanganate, which are not particularly soluble. If you add more solute that the solvent can dissolve, the molarity will stop increasing after the saturation point is reached.

If you keep adding more of the solute, it will just precipitate in the container, as the solvent will have dissolved the maximum quantity of material it is capable of.

If you are trying to teach the basic principles of chemistry to young students, an application such as this one can prove very helpful. It enables you to explain the concepts of molarity and solubility more intuitively, while also offering some examples that can be replicated in a chemistry lab.

The program is very easy to use, as you can set up an experiment with just a couple of mouse clicks, and it does not need to be installed before use, provided Java Runtime Environment is available on your PC.
