You are provided with four test tubes containing sugar solution, baking soda solution, tamarind solution, salt solution. Write down an activity to find the nature (acidic/basic/ neutral) of each solution.

The activity is given below:

• Take 4 test tubes.
• Add the sugar solution, baking soda solution, tamarind solution, salt solutions in different test tubes.
• Now add blue litmus solution and note down the change in colour.
• Then add red litmus solution and note the changes.

Observation: 

1. Sugar solution – No change in colour of blue or red litmus solution.
2. Baking soda solution – Turns red litmus blue.
3. Tamarind solution – Turns blue litmus red.
4. Salt solution – No change in colour of blue or red litmus solution.

Inference:

Sugar solution and salt solution – neutral

Baking soda solution – basic

Tamarind solution – acidic
