Wednesday 23 September 2020 – 4pm

CODE: 8020


This webinar will concentrate on the type of mathematical problems associated with the Amount of Substance topic.  The session will focus on the type of question which has a large amount of information and involves a multiple step calculation, part of which is the titration calculation.  The session will look at how to extract the relevant information from the question, how to work out what is being asked for and how to set out the answer to access all marks available for the question.


  • Consolidate and improve knowledge of Group 7 Chemistry
  • Promote understanding of Group 7 Chemistry to allow application to unfamiliar situations
  • Review exemplar questions and answers, finding out how to improve exam skills
  • Work through tips and examples for approaches to organic chemistry questions
  • Set a grounding for similar questions found in Year 13 study (i.e transition metals, acyl chlorides, etc)


  • All students of A level Chemistry


4.00pm – Introduction, welcome and sound check

4.00pm Welcome and Introduction

4.05 pm: Approaching the question

  • What is the question asking – how to extract the relevant information
  • Reading the question – how to avoid missing key points
  • Where to start – what do I know and what can I work out
  • Techniques to approach the question to help with structuring an answer
  • Pitfalls – Where do students lose marks in an exam

4.25pm: Setting out the answer

  • A look at worked examples to show how to be clear when answering the question
  • Hints and tips to ensure accuracy and precision
  • Checking the answer – tips to avoid silly errors which lose marks

4.40pm:  Trying it out

  • An opportunity for students to work through an example question
  • Modelling of the answer to show how to maximise marks

4.55pm: Final tips
