Formulas
- Titration: N₁V₁ = N₂V₂
- Group II cations precipitate with H₂S in acid

Key ideas
- Functional group tests: Tollens', Fehling's, FeCl₃, iodoform, carbylamine
- Salt analysis groups depend on reagents and solubility
- Indicators: phenolphthalein for strong base, methyl orange for strong acid
- Mohr's salt and oxalic acid titrations with KMnO₄
Traps to avoid
- Mixing group reagents
- Wrong indicator choice
- Forgetting the carbylamine test is only for 1° amines
