Around 15% of A Level Chemistry marks come from practical-technique questions in the written papers. Master these and you bank easy marks. 1. **Titrations** โ€” Rinse burette with acid, read to bottom of meniscus, discard first titre. 2. **Enthalpy** โ€” Extrapolate temperature-time graphs back to time of mixing. 3. **Rates by colorimetry** โ€” Calibrate with known concentrations, plot absorbance vs time. 4. **Organic synthesis** โ€” Reflux, distillation, separating funnel, drying agent, recrystallisation. 5. **Melting point determination** โ€” Use a capillary tube; sharp range confirms purity. 6. **Thin-layer chromatography** โ€” Calculate Rf; keep solvent below spot line. 7. **Electrode potentials** โ€” High-resistance voltmeter, salt bridge, standard conditions. 8. **Qualitative analysis** โ€” Systematic anion and cation tests in the right order.
