Objective: To teach the students about acids/bases/salts and their properties
Subtopics to be covered:
- Types of acids
- Indicators and natural indicators around us
- Neutralisation
Learning Outcome:
- Students know about various acids, bases and salts and their properties and uses .
- They should be able to give examples of acids, bases and salts from our everyday life.
-They know about pH value and its importance in our daily life
- They should be able to give examples of acids, bases and salts from our everyday 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.
