We have come across acids and bases many times. Some questions would have crossed your minds e.g. How do we compare the effects of acids and bases on indicators, How do we interpret chemical differences between acids and bases or How do we identity strength of acids and bases using indicators. The aim of this experiment is to find out answers to these questions.

Learning Outcomes

  1. Teaches how to look up pH values from a table.
  2. Teaches how to categorise acids and bases based on the pH values.
  3. Correlation between theory and practical becomes easier
