(a) When carbon dioxide is passed through lime water, calcium carbonate is formed, which makes lime water milky. The turning of lime water into milky is a standard test of carbon dioxide.
Carbon dioxide (CO2) + Lime water [Ca(OH)2] —> Calcium Carbonate (CaCO3) + Water (H2O)
(b) When baking soda is added to the acetic acid then carbon dioxide gas is formed which results in formation of bubbles.
Vinegar (Acetic acid) + Baking soda (Sodium hydrogencarbonate) —> Carbon dioxide + other substances
