Reaction between vinegar and Baking Soda:
Vinegar is an acid (Acetic acid). The chemical name of baking soda is sodium hydrogen carbonate or sodium bicarbonate.
When vinegar reacts with baking soda, it gives carbon dioxide. A hissing sound is produced when baking soda is added to vinegar. This happens because of production of carbon dioxide. When carbon dioxide is passed through lime water (calcium hydroxide), it turns the lime water milky. This happens because of formation of calcium carbonate. Water is also formed; along with calcium carbonate. The reaction involved in this can be written as follows:
CH3COOH + NaHCO3 → CH3COONa + CO2 + H2O
CO2 + Ca(OH)2 → CaCO3 + H2O
