Question

Why bubbles are formed when baking soda is added to vinegar ​

Answer 1

Answer:

Explanation:

Baking soda and vinegar react, and one of the products of the reaction is carbon dioxide gas. This gas forms bubbles that are surrounded by the liquid. The laundry detergent makes the bubbles last longer, and a foam is produced. ... Vinegar contains acetic acid dissolved in water.

Answer 2

Answer:

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
