Answer

Aim:

To find the nature of (acidic/basic/neutral) of each given solution (sugar, solution, baking soda solution, tamarind solution, salt solution).

Method:

With the help of a dropper put a drop of sugar solution on a strip of the blue litmus paper, no colour change. Now repeat the above step with red litmus paper, again no colour change will be observed. It indicates the sugar solution is neutral in nature.

Now, repeat the above activity with the other solutions. (Salt solutions, Baking soda solutions and tamarind solution.) We observe that

S. No.	Solution	Effect on red litmus solution	Effect on blue litmus solution	Nature of solution
1.	Sugar solution	No change	No change	Neutral
2.	Baking soda solution	Red litmus change to blue	No change	Basic
3.	Tamarind solution	No change	Blue litmus change to red	Acidic
4.	Salt solution	No change	No change	Neutral
