As you’ll already know from your GCSE chemistry studies, cations and anions are ions with opposite but complementary charges. When an atom loses one or more electrons it becomes a positively charged cation. On the other hand, if an atom
No, you shouldn’t pour acetone down the drain – and for very good reason. As acetone is highly flammable, it could potentially ignite and cause an explosion. It can also damage plastic plumbing and contaminate drinking water and the environment.
Chromatography is an important analytical technique that’s used to separate a mixture into its individual components. Its invention has contributed to scientific advances in various fields including the agricultural sector, biotechnology, food science, pharmaceuticals, and the chemical manufacturing industry. In
History and popular culture largely credit the discovery of the structure of DNA to the American biologist James Watson and the English physicist Francis Crick. They jointly received the 1962 Nobel Prize in Physiology or Medicine, along with fellow scientist
Although methanol and ethanol are both types of alcohol, there are some important differences between them. For starters, they have different chemical structures, properties, uses, and effects. Unlike ethanol, which is present in alcoholic beverages, methanol is extremely toxic and
Water purification refers to the removal of impurities such as dissolved minerals, sediment (mud), salts, microbes, and organic compounds from water. There are various ways to purify water, with common methods including filtration, distillation, desalination, and deionisation. If you’re studying
While boiled and distilled water are both subjected to heat, there are distinct differences between the two products. Boiled water refers to water that’s simply been heated to boiling point. Although this kills potential pathogens that can be harmful to
If you’re planning to pursue a career in chemistry, undertaking a chemistry internship is a great place to start. It allows you to enhance your theoretical knowledge by applying it to real-life problems in a working environment. By learning on
Ions are atoms, or a group of atoms, that have either gained or lost one or more electrons. Positively-charged ions are called cations, while negatively-charged ions are called anions. Being able to identify different types of ions is a key
