Chemistry

Chemistry KS3 at Common Entrance at 13+ is required for most of the top British boarding schools. The topics covered by IST tutors during the Chem lessons are particularly challenging for Hong Kong students because they are not usually covered by schools studying under the local HKDSE system. Topics taught during the lessons shall include: states of matter; atoms and elements; compounds and chemical substances; separating mixtures; types of reactions; the periodic table; acids, bases and neutralisation; pH scale; metals, ceramics, polymers, and composites; fossil fuels and the rock cycle; and organic chemistry.

Our IGCSE students shall develop these topics further to expand the depth and breadth of their knowledge of chemical terminology and scientific thinking skills. IGCSE topics may comprise of: ionic and covalent bonding; macromolecules; metallic bonding; stoichiometry; concept of moles; electrical charges; energetics of reactions; energy transfer; physical and chemical changes; rate of reaction; reversible reactions; types of oxides; preparation of salts; identification of ions and gases; periodic trends; group properties; transition elements; noble gases; properties of metals; reactivity series; extraction of metals; nitrogen and fertilisers; carbon dioxide and methane; sulfur; carbonates; fuels; homologous series; alkanes; alkenes; alcohols; carboxylic acids; and natural and synthetic polymers.

These topics shall be developed further for IB, SAT Subject Test, AP, and IAL students. In addition, topics such as: stereoisomerism; spectroscopic identification of organic compounds; redox processes; fundamentals of organic chemistry; Lewis acids and bases; acid deposition; transition metals; and equilibria. These topics shall help form a solid foundational base for future chemists that may be applied to help reduce climate change, carbon footprints, greenhouse gases; and help pharmaceutical research.

Chemistry is one of the most important subjects as it is required by most of the top medical schools in the world.
