Identifying Ions: Questions & Revision For GCSE Chemistry
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 part of the GCSE chemistry syllabus, so it’s important to

Chromatography: Questions & Revision For GCSE Chemistry
Chromatography is an important analytical technique that’s used to separate components of a mixture. Originally developed by Mikhail Tsvetin in 1900 to separate plant pigments, the method is actually a combination of two Greek words – chroma (colour) and graphein (to write). Hence, chromatography literally means ‘colour writing’. Continue reading

Mastering Electrolysis: A Practical Guide For GCSE Chemistry
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

GCSE Chemistry: Practical Skills
Chemistry wouldn’t be a real science if it were completely theoretical or abstract. Chemistry will always be about the real world, making it a practical subject requiring practical skills. Just like other natural sciences, its findings are based on empirical evidence and experimentation. Scientific method is the foundation of chemistry,

Chemistry GCSE Revision: Using Resources
Earth’s natural resources have limits in terms of availability, abundance, renewability, and carrying capacity. Although some resources are renewable, like geothermal power, trees, and the fish in the sea, many of mankind’s economic practices are exploitative and destructive, exceeding the sustainable limits of these resources. Sustainable Development Chemistry and other
