Activity 2.2 - How much acid do we find in a household product?

Learning Aims:

Here the focus lies on having the students state what they expect to find out.
Materials:

Experiment: see classroom material Activity 2.2
Suggestions for use:
  • Students must be able to calculate volume-concentration-relations.
  • Providing an opportunity for incorporating ICT: students could do titration with pH-meter to obtain digital neutralization curve (and use plotting software to digitalize results).
