GCSE Triple Chemistry: Chemical Analysis

This bundle contains all the content relevant to AQA Triple Chemistry students in the new 9-1 syllabus.

Includes 4 LESSONS worth of teaching materials:

This includes the standard tests and characteristic results/colour changes for:

• positive metal ion flame tests (Li, Cu, K, Na, Ca),
• positive metal ion precipitate tests with NaOH (Fe(III), Fe(II), Cu(II), Mg, Ca, Al)
• sulfate test with barium nitrate/chloride
• halide tests (Cl, Br and I) with silver nitrate
• carbonate tests with dilute acid and lime water

These lessons contain full powerpoints, student worksheets, complete answers, risk assessments/technician order forms, stretch and challenge tasks, relevant exam questions, and AfL plenary activities

Lesson 1-2: Identifying positive metal ions (flame tests and precipitate tests)
Lesson objectives:

• Carry out simple flame tests to identify positive metal ions
• Carry out simple precipitate tests to identify positive metal ions
• Describe how to carry out a flame test and a precipitate test, including the names of any important reactants
• Describe the problems and limitations of using flame tests and precipitate tests to identify positive metal ions

Lesson 3 - Identifying negative non-metal ions
Lesson objectives:

• Carry out simple precipitate tests to identify halide, sulfate and carbonate ions
• Describe how to carry out precipitate tests to test for halide, sulfate and carbonate ions, including the names of any important reactants
• Write balanced symbol and ionic equations for the reactions taking place in precipitation reactions

Lesson 4 - Instrumental Analysis and Flame Emission Spectra
Lesson objectives:

• Know what instrumental techniques are
• Describe advantages and disadvantages of instrumental techniques over other analysis techniques (e.g. flame tests)
• Interpret flame emission spectra to identify unknown elements in a mixture

Lesson resources include:

• Complete and full powerpoints - including starter activities, challenge activities, tables of results, practical instructions, questions with complete answers
• Student worksheets and practical sheets with instructions and tables for results (PDF and editable word versions)
• Student worksheet answers (PDF and editable word versions)
• Practical risk assessments/order forms (up to date with CLEAPPS data as of Oct 2023)
• Relevant practice exam questions with mark schemes and examiners reports.
