Possible pracs:
- Testing pH of several substances using indicators.
- Producing and using a natural indicator.
- Mass changes involved with opening a soft drink can.
- Measuring the pH of identical concentrations of strong and weak acids.
- Titration using acids and bases.
- Esterification using an alkanol and an alkanoic acid.
A hard prac would be titration mixed with strong/weak acids - something like giving you several solutions of unknown concentration, asking you to find the concentration by titration and then comparing pH.
You really just need to know the methods and techniques.
