Question

using the knowledge of acids and bases write a secret message with the help of baking soda and beetroot​

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.
