Question

Using the knowledge of acids and bases, write a secret message with the help of baking soda and beet root. Explain how it works (Hint: Prepare baking soda solution in water. Use this solution to write the message on a sheet of white paper with a cotton bud. Rub a slice of fresh beet root over the message.)

Answer 1

In this experiment, we can use baking soda and the turmeric powder is used as a base. At first, we have to take a yellow sheet of paper and then apply a little amount of the turmeric powder solution to create the message.

Then for seeing the baking soda, we can apply the solution of soda so that it can turn red.

This is because the turmeric acts as an indicator and when the base is added to it changes its color to red.

Answer 2

Baking soda is utilised as a base in this experiment, while turmeric powder is used as a base. To make the message, we must first take a yellow sheet of paper and add a small bit of the turmeric powder solution to it.

Then, in order to observe the baking soda, we can use a soda solution to colour it red.

This is because the turmeric functions as a colour indicator, changing to red when the base is applied.
