Question

when baking soda added to vinegar
​

Answer 1

Baking soda is sodium bicarbonate NaHCO3 (a base) and vinegar is diluted acetic acid CH3COOH (weak acid).

When they react to release the OH and H to become water, they also release carbon dioxide.

This makes the reaction bubble and expand, just like when you shake up a can of soda and open it!

Hope it helps.....
