Question

Bubbles are seen on adding lemon juice to baking soda

Answer 1

Approximately 5 percent of lemon juice is citric acid, which accounts for the sour taste of the lemon. When you mix an acid and a base, the result is a chemical reaction that creates a new product, with a neutral base. In the case of lemon juice and baking soda, the new product is carbon dioxide gas, water and salt.

Answer 2

bubbles are seen because lemon is a acid which reacts with base that is baking soda
