Chemical uses, chemistry information and industry news
Whether you’re studying for a chemistry degree or you’ve recently graduated, a chemistry internship is a great way to gain practical experience and learn new skills in your preferred industry.Some students choose to undertake a chemistry internship during their summer holidays, while others wait until after they’ve graduated. Either way, the valuable on-the-job training you’ll receive will give you a...
Fractional distillation is the separation of various components from a liquid. Each component typically has a different boiling point and vapour pressure than the rest, so fractional distillation can be achieved by applying a temperature gradient.The various components are condensed at different stages or levels of the setup, which can either be a small setup consisting of laboratory glassware and...
The pH of brick acid varies depending on factors, such as temperature and concentration. Commercially available brick acid typically has a pH range of between 0 and 2. However, highly concentrated brick acid of more than 36% by mass can have a negative pH (below 0).As the name suggests, brick acid is normally used to remove stains and mineral deposits...
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...
