Explain the following:
(a) Lime water turns milky on passing carbon dioxide gas into it.
(b) Bubbles are produced when acetic acid is added to a solution of sodium hydrogen carbonate.
(a) When carbon dioxide gas is passed through lime water, it turns milky because a white precipitate of calcium carbonate is formed.
Calcium hydroxide + Carbon dioxide →Calcium carbonate + Water
(b) When acetic acid is added to a solution of sodium hydrogen carbonate, carbon dioxide gas is formed which comes out in the form of bubbles.
Sodium hydrogen carbonate + Acetic acid → Sodium carbonate + Water + Carbon dioxide
