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.

Answers (1)

Add blue litmus solution and red litmus solution for the test tubes containing sugar solution, baking soda solution, tamarind solution, salt solution. Below observations will be observed with respect to colour changes in each of them.

Sugar and salt solution is neutral so no colour change will be observed. 

Baking soda turns red litmus to blue so it is a basic solution.

Tamarind solution turns blue litmus to red so it is acidic in nature
