Even if you’re not a chemist, you’ll doubtless remember learning about acids back in school. They’re routinely described as strong or weak, concentrated or dilute. But what’s the difference between a strong acid and a concentrated acid? Explaining that is a little trickier than it sounds; in this graphic, we give it a go!
Here’s the latest graphic from Chemunicate (the Compound Interest side project that works with chemistry researchers and institutions to highlight their research in graphical form). This graphic is a collaboration with the Cambridge Crystallographic Data Centre (CCDC) and looks at their recent research on capturing neon in a metal-organic framework – and why it matters! You can read the CCDC’s press release for the study here, and the study itself can be found here.
Know your sulfates from your sulfites, and your chlorates from your perchlorates? This graphic gives a helping hand with remembering the names, formulae and charges of various different polyatomic ions. The selection covers all of the ions GCSE students are likely to come across, as well as the vast majority of those that will be encountered by A level students.
Limescale is a substance you’ve undoubtedly encountered, be it clogging up your kettle, or building up on your bathroom surfaces. But how does it get there in the first place, and how do limescale removers work to get rid of it? Those are the questions this graphic aims to answer.
The metal reactivity series is a commonly taught concept in chemistry, placing the metals, as its name suggests, in order of reactivity from most reactive to least reactive. It’s also a useful tool in predicting the products of simple displacement reactions involving two different metals, as well as providing an insight into why different metals are extracted from their ores in different manners. This graphic places a selection of common metals into order of reactivity, as well as showing their reactions with air, water and steam.
Coloured glass is something that’s commonplace in our lives, from the green of wine and beer bottles, to the red, yellow, and green of traffic lights. The origin of these colours is something we don’t give a lot of thought to, but a range of different elements are responsible. This graphic takes a simple look at a few of these, and the colours they impart.
