pH and indicators

The resources in this list allow students to investigate the pH scale, acidity, alkalinity, and indicators. This is often students' first chance to get hands on with chemistry in Year 7 and always creates a bit of a buzz in the classroom. The list provides a range of activities, lesson ideas, film clips, background information and practical tips.

The resources are linked to these topics:

  • defining acids and alkalis in terms of neutralisation reactions
  • the pH scale for measuring acidity/alkalinity; and indicators
  • reactions of acids with metals to produce a salt plus hydrogen
  • reactions of acids with alkalis to produce a salt plus water

Whilst this list provides a source of information and ideas for experimental work, it is important to note that recommendations can date very quickly. Do NOT follow suggestions which conflict with current advice from CLEAPSS, SSERC or recent safety guides. eLibrary users are responsible for ensuring that any activity, including practical work, which they carry out is consistent with current regulations related to health and safety and that they carry an appropriate risk assessment.
