Question

Study the following properties of acetic acid (ethanoic acid) 1) odour 2) solubility in water 3) effect on litmus 4) reaction with sodium hydrogen carbonate

Answer 1

1. odour - smells like vinegar
2.Soluble in water and furnishes H+ ions in it.
3. turns blue litmus red
4. CH3COOH + NaHCO3 gives CH3COONa + H2O + CO2

Answer 2

Answer:

Explanation :Properties of Ethanoic Acid (CH_{3}COOH)

(a)  Odour  : It has pungent smell

(b) Solubility in water : It is soluble in water due to formation of hydrogen bonding.

(c) Effect on litmus paper

       It turns blue litmus red, indicating that is acidic in nature.

       CH_{3}COOH\ right left harpoons CH_{3}COO^{-}+H^{+}

When dissolved in H_{2}O, acetic acid undergoes dissociation to form H^{+}, ion due to release of H^{+},CH_{3}COOH is acidic in nature.

(d) Reaction with sodium hydrogen carbonate

   CH_{3}COOH+NaHCO_{3}\rightarrow CH_{3}COONa +CO_{2}+H_{2}O
