Answer 1

Answer:

This is because beetroot performs as an indicator of acids and bases. It turns all acidic solutions red. The solution will also become red in case of lemon juice as because it contains citric acid. In case of baking soda and soap water , the solution in the vessel will turn green as because they are bases.
