Common physical changes include melting, change of size, volume, color, density, and crystal form. The classic baking soda and vinegar reaction provides evidence of a chemical change due to the formation of a gas and a temperature change
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.
