Chemistry
TOF Time of flight Mass spec calculations
A resource applicable for the current AQA A-Level Chemistry specification on TOF Mass spec calculations. The questions test students on how to calculate velocity, distance of flight tube, time taken and atomic mass. Answers are included to every question including a hand-written extended answer sheet showing each step of the calculations to assist students who get stuck. The resource usually takes about 60 – 90 mins for students to complete depending on their ability.
Bundle
Titration bundle
A bundle of three resources for A-Level Chemistry. Suitable for all Exam boards. Two of the resources are on titration calculations, the third is a hexagon activity. Students complete titration calculations on determining volume, concentration, Mr of a compound, percentage purity, formula of a compound (working out the value of n in Na2CO3.nH20), redox titrations etc. Answers are included for all the calculations.
A-Level Chemistry Titration calculations
An A-Level Chemistry resource on titration calculations suitable for all specifications. The worksheet is differentiated with each section increasing in difficulty. Students complete titration calculations on determining volume, concentration, Mr of a compound, percentage purity, formula of a compound (working out the value of n in Na2CO3.nH20) etc. The resource contains one of every type of titration question they need to answer in an exam. Answers are included. There are 6 different sections and the worksheet takes a standard double lesson for students to complete.

Kinetics knowledge organiser
An A-Level Chemistry knowledge organiser about Kinetics. Contains information on rates of reaction (factors that affect the rate, experimental methods, explanations of why these factor affects the rate etc.) Also contains informaiton on Maxwell Boltzmann distributions and how they are used to explain the effect of temperature and a catalyst.
Topic 10 equilibrium knowledge organiser
An Edexcel A-Level Chemistry knowledge organiser on equilibrium. Covers all the content about equilibrium from topic 10 including using Le Chatelier’s principle to determine the effect of temperature, concentration, pressure and a catalyst on the position of equilibrium. Includes examples and information about the Haber compromise. Also includes information on how to write the Kc expression.
Oxidation and reduction knowledge organiser
An A-Level Chemistry knowledge organiser on oxidation and reduction. Includes information on assigning oxidation number rules, oxidation and reduction, oxidising and reducing agents, disproportionation, writing half equations (in both acidic and alkaline conditions) and combining half equations to write a full ionic equation. Suitable for all exam boards.
NMR graphic organiser
A graphic organiser on the A-Level Chemistry concept of 1H NMR. A visual aid that illustrates the main points that students need to know about the theory of NMR (solvents, TMS, D2O, splitting pattern, integration etc).
NMR knowledge organiser
A knowledge organiser on NMR spectroscopy suitable for A-Level Chemistry syllabuses. Includes information about the theory of 1H (proton) NMR. Includes explanation of how NMR works (property of spin, magnetism and radio waves). Also contains information about TMS, solvents, labile protons, Low and high resolution, spin-spin coupling, n+1 rule, splitting patterns, integration etc.
Aspirin synthesis
A knowledge organiser on the A-level chemistry practical “preparation of aspirin" from 2-hydroxybenzoic acid and ethanoic anhydride using a phosphoric acid catalyst. The knowledge organiser includes the method and apparatus diagrams and goes into more depth about filtration under reduced pressure, recrystallisation and reflux. I use it in my lessons to go through the procedure in greater depth and then students refer to this when practising questions.
Bundle
Preparation of a pure organic liquid
A bundle of resources on the A-Level chemistry required practicals “preparation of a pure organic liquid”. In the A-level exams students will be tested on an organic preparation and this resource helps prepare students for any of the options that could come up in the exam. There are a set of 6 knowledge organisers based on the following practicals: Oxidation of ethanol, oxidation of butan-2-ol, preparation cyclohexene, preparation of iodobutane, preparation of bromobutane and chlorination of 2-methyl-propan-2-ol. Each knoweldge organiser contains the method, apparatus diagram and additional information about the purpose of refluxing, distillation , washing, drying etc. Each step in the practical is explained.
