What each required practical measures, hazards and control measures, improving methods and planning.
The practicals at a glance
- Making a soluble salt, titration, electrolysis, temperature change, rates (two ways), chromatography, identifying ions, water purification.
- For each one, know: what you change, what you measure, what you keep the same, the main source of error, and one hazard with its control.
Improving an experiment usually means removing a source of error you can name, not "doing it more carefully".
