Testing for Positive Metal Ions

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.
