Question

What happens if :
i) Baking soda is mixed with lemon juice.
ii) Supersaturated copper sulphate is cooled and kept undisturbed for sometime

Answer 1

Answer:

1When baking soda (Sodium bicarbonate) is mixed with lemon juice(citric acid), bubbles are formed. These bubbles are formed due to the evolution of carbon dioxide gas. This is a chemical change.

2As this supersaturated solution cools, the excess solute will remain dissolved until a disturbance, such as the addition of more solute. You can create a supersaturated solution of copper(II) sulfate in this way.
