Comprehensive slides that provide a great introduction to this topic for either A-level or IB Chemistry (with some cat photos). **Detailed explanations of: ** Uncertainty (absolute and relative/percentage) Random and systematic error Accuracy and precision Percentage error Specific focus on Titration Everything with worked examples. I have focused on the Titration practical method and calculation as this is commonly asked about. The slides finish with a quiz to assess knowledge.

A couple of novel mnemonics with some humor to help revise the colours of the flame tests. This involved aligning Rainbow (ROYGBIV) with a new mnemonic for the flame colours as well as the classic Corgi mnemonic. Designed for AQA but could work equally well for IGCSE Edexcel.

A set of slides helping revise all the common tests for gases , followed by all the cations and anions on the AQA spec. I have added in some novel mnemonics, revision tips and cat pictures/humour to help with recall. It finished with a multiple choice quiz to for assessment. Common gases: Hydrogen, Oxygen, Carbon dioxide, Chlorine. Cations: Flame tests for Lithium, Sodium, Potassium, Calcium, Copper; Sodium hydroxide precipitates: Aluminium, Calcium, Magnesium, Copper, Iron (II), Iron (III). Anions: Halides, Sulfates, Carbonates.

Single slide that uses an excellent mnemonic to remember the solubility rules for all ionic compounds on the Edexcel GCSE and IGCSE specifications, including all exceptions. “Some Curious Animals Never Get Cold Hands”

A concise summary of all types of chemical reaction in one place, with examples, followed by a quick quiz to assess knowledge. Great for a revision session as this is not usually taught as a single topic. Aimed at IB Chemistry level but also suitable for A-level. Reactions covered: Synthesis Decomposition Single displacement Double displacement Combustion Redox Disproportionation Neutralisation Precipitation Complexation Electrophilic addition Nucleophilic substitution Elimination Nucleophilic addition

Worksheet with an introduction explaining the CORMMS mnemonic, followed by 8 high-quality exam-style questions and answers.
