Science behind it
Baking soda often called by other names such as sodium bicarbonate or
bicarbonate of soda. (NaHCO3)
Baking soda is an alkaline substance when mixed with acids change the pH
levels and that is the reason it became a quickest remedy for illnesses like
stomach upset, bad smell etc.
The process of combining baking soda and vinegar forms a cloudy liquid and
produces carbon dioxide
The bubbles and foam you see are filled with carbon dioxide gas (CO2) that’s being released
by an acid/base reaction. Vinegar is acetic acid dissolved in water and baking soda is a base
called sodium bicarbonate. Initially, the reaction makes carbonic acid which is unstable. It
quickly breaks down into CO2 and water. The gas then rapidly leaves the water creating
foam and bubbles along the way.
