Question

When baking soda is mixed with lemon juice, bubbles are formed with the evolution of a gas. What type of change is it?. Explain. ​

Answer 1

Explanation:

When 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.

In the change, the citric acid contained in lemon juice reacts with the baking soda or sodium bicarbonate) which results in the evolution of carbon dioxide gas.

Lemon Juice + Baking soda → Carbon dioxide + Other substances

Answer 2

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

In this change, citric acid contained in lemon juice reacts with sodium hydrogen carbonate which results in the evolution of carbon dioxide gas.

Lemon juice + Baking soda → Carbon dioxide + Other substances

Citric acid Sodium

Hydrogen carbonate
