A concise set of slides covering the theory of sp1, sp2 and sp3 hybridisation, linking to shape of molecules. Arranged in a way that is easy to understand and includes relevant examples.
Would suit AQA, OCR, Edexcel, Cambridge or IB specifications.
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.
Worksheet with an introduction explaining the CORMMS mnemonic, followed by 8 high-quality exam-style questions and answers.
I have added some hints to the questions so that the questions are more accessible to younger students who have not necessarily completed all of the required practicals.
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
