why did bubble come when we mix baking soda and vinagiri

Baking soda {sodium bicarbonate} is a base and vinegar {acetic acid} is an acid. When combined, they react to form water, a salt {sodium acetate}, and carbon dioxide gas. The bubbles produced by the reaction {in the bottle} are the carbon dioxide gas escaping the water. As the gas is formed, the air already in the plastic bottle is pushed up. As the air passes through the soapy washcloth, soap bubbles are formed.
