Answer:

this experiment, we can use baking soda and the turmeric powder is used as a base.

Answer 2

~Answer :-

Here, we can do this experiment as follows;

• Take a sheet of yellow colour.
• Now, write a secret message using turmeric powder.
• Now, after using the knowledge of acid and bases, we can heat the paper and can see the secret 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.
