Question

Take vinegar, lemon juice, soapy water, baking soda in different vessels. Put beetroot pieces in the vessels. Predict what happens? Verify your prediction by observing the changes. After 10 minutes, 30 minutes, 60 minutes record your observations. What do you conclude.

Answer 1

After carrying out the experiment, u would see that the vessel with beetroot juice and vinegar will turn the whole solution red.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. Hence you can conclude that beetroot is an indicator which turns acidic solutions red and base solutions green..
