Analytical chemistry and precipitation: Solubility rules, overall and net ionic equations, spectator ions, flame tests and gas tests

What this note covers

1. Where analytical chemistry sits in Criterion 7, and the tools you are given
2. Reading the solubility table properly
3. Predicting the precipitate: swap the partners, then check the table
4. Overall, complete ionic and net ionic equations, and spectator ions
5. A worked set: three precipitations with different charge ratios
6. Flame tests and gas tests: the procedure, and what the observation proves
7. Identifying an unknown inorganic compound: a systematic scheme
8. How Section D examines this — and what separates a top answer
