What does your textbook say about Carbon and its Compounds?
Activity . Set up the apparatus as shown in Chapter , Activity . . Take a spatula full of sodium carbonate in a test tube and add mL of dilute ethanoic acid. What do you observe? Pass the gas produced through freshly prepared lime-water. What do you observe? Can the gas produced by the reaction between ethanoic acid and sodium carbonate be identified by this test? Repeat this Activity with sodium hydrogencarbonate instead of sodium carbonate. (iii) Reaction with carbonates and hydrogencarbonates : Ethanoic acid reacts with carbonates and hydrogencarbonates to give rise to a salt, carbon dioxide and water. The salt produced is commonly called sodium acetate.
