What should I know before I study this Unit?

As this unit builds on AS unit 2, it’s a really good idea if you have can:

  • Identify metal ions

  • Carry out a titration and work out concentrations, given the correct formulae

  • Understand what a hydrocarbon is

What will I be studying in this Unit?

In a nutshell you will be studying the following areas:

  • How a functional group gives an organic chemical unique properties

  • How to identify a functional group in an organic chemical

  • How to identify metal ions

  • How to work out the concentration of metal ions using redox titration

  • How to identify such an ion in an unknown compound and then work out its concentration

  • How ‘real’ forensic investigations are carried out by analyzing a TV programme or book

How long will this Unit take to study?

On average you’ll be looking at 60 hours of teaching and independent research time.

What topics will I be studying in this Unit?

Topic 1: Functional grouping

Topic 2: Ion identification

Topic 3: Quantitative analysis

What can I do to get the best out of this Unit?

If you’re really serious about getting the best out this Unit and are prepared to put some extra time in on your own, it would be great if you could do some of the following:

  • Organise visits by companies involved with forensic analysis

  • Work in teams with defined team roles and evaluate their performance as part of the team

  • Produce risk assessments using appropriate Health & Safety guidance

  • Communicate remotely with others to organise an activity
