Acetone, also known as propanone, is the simplest and the smallest type of ketone. The solvent’s ability to break down polymers means it can remove a range of stubborn substances such as paint, varnish, and nail polish. Acetone can also be used to remove glue, including stronger varieties like superglue (cyanoacrylate). Continue reading to learn more about acetone and why it’s...
Electrolysis is a process that uses an electrical current to separate ionic compounds into their constituent elements.When a direct current is passed through an ionic substance, the ions migrate to the oppositely charged electrode and drive a non-spontaneous oxidation-reduction reaction.If you’re studying GCSE chemistry, you may have already used electrolysis to separate oxygen and hydrogen from water. However, the technique...
Polyethylene glycol (PEG) is a hydrophilic synthetic compound with a wide range of commercial applications. The chemical’s ability to absorb water means it’s often used in cosmetic products, where it acts as a cleansing agent, skin conditioner, and emulsifier. PEG is also a common ingredient in parenteral medications and laxatives. Continue reading to learn more about the common uses of polyethylene...
As part of your GCSE chemistry studies, you’ll need to have a good understanding of why temperature changes occur during a chemical reaction. After all, a rise or fall in temperature is one of the important and measurable indicators of chemical change.Conducting your own experiment is a great way to learn about the science behind temperature change in chemistry. In...
As part of your GCSE chemistry studies, you’ll need to have a good understanding of neutralisation and how it works. One of the most effective ways to achieve this is to conduct your own neutralisation reaction - after all, there’s no substitute for practical, hands-on experience.In this article we explain what neutralisation is and provide step-by-step instructions on how to...
Nitric acid has a wide range of industrial applications, although it’s primarily used in the manufacture of fertilisers as a precursor to ammonium nitrate. In fact, fertiliser production accounts for around 80% of the total global use of nitric acid. The chemical is also used to manufacture furniture coatings and certain types of plastics.Continue reading to learn more about the...
Formaldehyde can be found in a variety of common household items including certain types of furniture, hygiene and cosmetic products, gas ovens, candles, and air fresheners. It’s also naturally present in fruits and vegetables such as bananas, apples, and carrots.Although formaldehyde is toxic in high concentrations, it’s relatively harmless at low levels. That being said, it’s important to be aware...
Whether you’re revising for your GCSE chemistry exam or writing up an experiment, you’ll need to have a good understanding of some key chemistry terms. But if you don’t know your hydrocarbons from your valence electrons, don’t worry - this handy GCSE chemistry glossary is here to help.Covering a range of key topics, this page outlines some basic GCSE chemistry...
The functions of the human brain, including emotions, are regulated by neurotransmitters that pass chemical messages around the body. Depression, for example, has been linked to a chemical imbalance in mood-regulating neurotransmitters like serotonin and dopamine. This imbalance may be the result of a genetic disorder, drug abuse, a traumatic life event, or - as many researchers believe - a...
