O Level Chemistry on QuizByt covers 12 topics, from Atomic Structure & Bonding through to Reversible Reactions & Equilibrium. It is matched to Cambridge and Oxford standards, built with AI and reviewed by real teachers of the subject. Every topic has a step-by-step lesson to read, practice quizzes at three levels, and printable worksheets with an answer sheet. Quizzes mark themselves and record a score for each topic, so it is clear which part needs more work rather than only that the subject does.
Topics covered in O Level Chemistry 12
Atomic Structure & Bonding
Protons, electrons and the three kinds of bond, the section every later topic assumes, and the one where a dot-and-cross diagram is worth as much as an essay.
States of Matter
The particle model, diffusion, purity and the separation techniques, the practical-paper section, where knowing why a method works is the difference between a description and an explanation.
Stoichiometry & the Mole
Formulae, balanced equations, and the mole as the hub of every calculation, the section that turns up in every other topic and where working shown is the whole mark.
Electrochemistry
What is discharged where, and why, plus cells and fuel cells. A short topic with a strict logic, so it is one of the easier places to score full marks.
Energetics & Rates of Reaction
Exothermic and endothermic, bond energies, and collision theory, two sections the paper loves to combine into one graph question.
Acids, Bases & Salts
Definitions in terms of ions, the three reactions of acids, strong versus weak, the salt preparations and the ion tests, the most practical-heavy section on the paper.
The Periodic Table
Groups, periods and the trends down Group I and Group VII, explained from electron shells, the section where "describe" and "explain" are two different marks.
Metals & Reactivity
The reactivity series, displacement, extraction of iron and aluminium, rusting and its prevention, the section that links the periodic table to industry.
Chemistry of the Environment
Air, water, pollution, the Haber and Contact processes and fertilisers, the section that asks for chemistry and consequences in the same answer.
Organic Chemistry
Crude oil, the homologous series, alkanes, alkenes, alcohols, acids, esters and polymers, a topic of naming, drawing and one reaction type per family.
Experimental Techniques & Chemical Analysis
Reversible Reactions & Equilibrium
