What Temperature Does Water Boil At? Boiling Point & Elevation

Water always boils at 100˚C, right? Wrong! Though it’s one of the basic facts you probably learnt pretty early on back in school science lessons, your elevation relative to sea level can affect the temperature at which water boils, due to differences in air pressure. Here, we take a look at the boiling points of […]

Making Reactions Faster: Factors Affecting Rates of Reaction

How different factors can affect how quickly a reaction happens is a common topic in the chemistry curriculum. This graphic serves as a convenient summary for teachers and students alike of what these different factors are, and how and why they affect the rate of a reaction. However, it’s not only of interest to those […]

A Guide to the Different Types of Radiation

We’re venturing tentatively into the border region between chemistry & physics today, with a look at some of the different types of nuclear radiation. These types vary in their composition, characteristics, and uses, but here’s an attempt to sum up the most common in one succinct graphic.

Acids, Alkalis, and the pH Scale

The pH scale is something we’re all familiar with; most people will remember it from school chemistry lessons. It’s the scale used to rank how strong an acid (or alkali) a solution is. The colours associated with each number correspond to the colour that universal indicator turns in solutions of that particular pH. A fair […]
