1.	Sodium hydrogen carbonate when added to acetic acid evolves a gas. Which of the following statements are true about the gas evolved? (i) It turns lime milky (ii) It extinguishes a burning splinter (iii) It dissolves in a solution of sodium hydroxide (iv) It has a pungent odour.
Answer» (i) and (ii) (i), (ii) and (iii) (ii), (iii) and (IV) (i) and (iv) Solution :When sodium hydrogen carbonate is added to acetic acid then carbon DIOXIDE `(CO_(2))` GAS is evolved. `NaHCO_(3)+CH_(3)COOHrarrCH_(3)COONa+CO_(2)+H_(2)O` `CO_(2)` turns lime water milky it is a non supporter of combustion and is absorbed by strong ALKALIES like NaOH.
