उत्तर
Properties of Ethanoic Acid (CH3COOH)
(a) Odour : It has pungent smell.
(b) Solubity in water It is soluble in water due to the formation of hydrogen bonding.
(c) Effect on litmus paper
∗ It turns blue litmus red, indicating that it is acidic in nature
CH3COOH \[\rightleftharpoons\] `CH_3COO^(-) + H^+`
∗ When dissolved in water, acetic acid undergoes dissociation to form `H^+` ion . Due to the release of `H^+` , CH3COOH is acidic in nature .
(d) Reaction with sodium hydrogen carbonate
CH3COOH + NaOHCO3 → CH3COONa + CO2(g) + H2O(l)
