Area 1: Chemical Changes and Structure
Module overview β- What makes a solution acidic or alkaline, and what happens when they react?Acids and bases: the pH scale and the effect of dilution, forming acids and alkalis from oxides, neutralisation and naming salts, spectator ions, and titration calculations.12 min answer β
- What is an atom made of, and how do we describe its particles?Atomic structure: protons, neutrons and electrons; atomic number and mass number; electron arrangement of the first 20 elements; isotopes and relative atomic mass.10 min answer β
- How does the bonding and structure of a material explain its properties?Bonding and properties: covalent bonding (molecular and network), ionic bonding, and how each structure explains melting point, conductivity and solubility.11 min answer β
- How do the key areas of Area 1 fit together into the quantitative and structural core of the course?Overview of Area 1 Chemical Changes and Structure: how rates of reaction, atomic structure, bonding and properties, formulae and reacting quantities, and acids and bases connect.9 min answer β
- How do we write formulae and work out the quantities that react?Formulae and reacting quantities: chemical formulae using valency and the data booklet, balanced equations with state symbols, the mole and gram formula mass, and concentration of solutions.12 min answer β
- What controls how fast a chemical reaction goes, and how do we measure it?Rates of reaction: following the course of a reaction, calculating average rate, and explaining the effects of concentration, particle size, temperature and catalysts using the idea of collisions.11 min answer β
Area 3: Chemistry in Society
Module overview β- How do chemists test for substances and monitor the environment?Chemical analysis: general practical techniques, gas tests and flame tests, paper chromatography, and the use of analysis to monitor the environment.11 min answer β
- How do the key areas of Chemistry in Society apply chemistry to materials, industry and analysis?Overview of Area 3 Chemistry in Society: how metals, electrochemical cells, metal extraction, plastics, fertilisers, nuclear chemistry and chemical analysis connect.9 min answer β
- How can a chemical reaction produce electricity?Electrochemical cells: how two different metals in an electrolyte produce a voltage, the role of the ion bridge, and using the electrochemical series to predict the direction of electron flow.11 min answer β
- How does chemistry help feed a growing population, and at what cost?Fertilisers: the essential elements nitrogen, phosphorus and potassium, the Haber process for ammonia, the Ostwald process for nitric acid, nitrogen fixation, and environmental problems such as eutrophication.11 min answer β
- How do we get a metal out of its ore, and why does the method depend on reactivity?Extraction of metals: ores, how the method of extraction depends on the reactivity series, reduction by heat, reduction by carbon or carbon monoxide, and electrolysis for very reactive metals.11 min answer β
- How do metals react, and how do we put them in order of reactivity?Metals: properties and uses, the reactivity series, reactions with oxygen, water and acids, displacement reactions, and oxidation and reduction with ion-electron equations.12 min answer β
- What is nuclear radiation, and how do we describe how fast a sample decays?Nuclear chemistry: alpha, beta and gamma radiation and their properties, radioactive decay as a random process, half-life and half-life calculations, and the uses and dangers of radiation.11 min answer β
- How are plastics made from small molecules, and what problems do they cause?Plastics: synthetic materials made by addition polymerisation, monomers and polymers, the repeating unit, uses of common plastics, and the problems of disposal.10 min answer β
Area 2: Nature's Chemistry
Module overview β- What makes a molecule an alcohol, and how are alcohols named and used?Alcohols: the hydroxyl functional group, naming the straight-chain alcohols, their properties and their uses as solvents and fuels.10 min answer β
- What makes a molecule a carboxylic acid, and how do these acids react?Carboxylic acids: the carboxyl functional group, naming the straight-chain acids, their reactions with bases to form salts and water, and everyday examples such as vinegar.10 min answer β
- Where does the energy in fuels come from, and how do we measure it?Energy from fuels: fossil fuels as finite resources, complete and incomplete combustion, exothermic reactions, and calculating the energy released using Eh equals cmDeltaT.11 min answer β
- How are families of carbon compounds named, and how do we tell saturated from unsaturated?Homologous series: alkanes, cycloalkanes and alkenes, their general formulae and naming, saturated and unsaturated molecules, isomers, addition reactions and the bromine test for unsaturation.12 min answer β
- How do the key areas of Nature's Chemistry build a picture of carbon compounds and fuels?Overview of Area 2 Nature's Chemistry: how the homologous series, alcohols, carboxylic acids and energy from fuels connect through functional groups and combustion.9 min answer β
Skills of Scientific Inquiry and the Assignment
Module overview β- What practical and data skills does the course test alongside the chemistry?Skills of scientific inquiry: planning and variables, presenting data in tables and graphs, processing calculations, drawing conclusions, and evaluating reliability.11 min answer β
- What is the National 5 Chemistry assignment, and how is it marked?The assignment: the controlled-conditions report worth 20 marks, its sections from aim to evaluation, and how marks are awarded for data, analysis and conclusions.10 min answer β
