A fun song I wrote for my science classes to help introduce the concept of dissolving solids in water (salt and sugar). LYRICS: I like to dissolve things, Just like scientists like to solve things, And I’m using H2O, That’s just water,...

In this video Paul Andersen explains how ionic solids form a lattice between cations and anions. According the Coulomb's Law the lattice energy increases as the ions carry a larger charge and are smaller. Some of the properties of...

We know about solutions and solubility, but we have typically examined solid or liquid solutes dissolved in a liquid solvent. Did you know that gases can also be dissolved in liquids? Their solubilities depend heavily on temperature, so...

Learn about energy diagrams, calculating molar heat of vaporization and fusion and molar heat of solution in this video! Transcript ______________ In this diagram we have the temperature of water in degrees celsius on the side and energy...

Separation techniques are important in chemistry, and they won't always be as easy as filtration. Sometimes we need to separate two compounds that are dissolved in the same solution. Often we can take advantage of a difference in...

Molecules come in infinite varieties, so in order to help the complicated chemical world make a little more sense, we classify and categorize them. One of the most important of those classifications is whether a molecule is...

Glass is made by heating sand (mostly composed of silicon dioxide) until it melts and turns into a liquid at a high temperature of around 1700° Celsius. When the molten sand is allowed to cool, it becomes an amorphous solid, featuring...

- How evaporation can be used to separate a soluble solid from
a solution
- How crystallisation can be used to separate a...

In this video, we will look at the state symbols (s), (l), (g), and (aq) and what they represent in a chemical equation. For equations to be complete, we must also include the state symbol for each reactant and product. There are four...

In this video Paul Andersen explains the important properties of solutions. A solution can be either a solid, liquid or gas but it must be homogeneous in nature. The solutes can not be separated with a filter and so either...
