Objective: To teach the students about the difference between Acids, Bases and Salts
Subtopics to be covered:
- Indicators and natural indicators around us
- Neutralisation, examples from everyday life
Learning Outcome:
- Students can classify items into acids, bases and salts .
- They should be able to give examples of acids, bases and salts from our everyday life.
- They know about neutralisations that happen in our day to day life.

1. Ask students to name some common objects that contain acids, bases and salts.
2. Take a tablespoonful of turmeric powder. Add a little water and make a paste. Make turmeric paper by depositing turmeric paste on blotting paper/filter paper and drying it. Cut thin strips of the yellow paper obtained. Put a drop of soap solution on the strip of turmeric paper. What do you observe?
3.Name some common objects containing neutral components.
