Give important properties of ethanoic acid (Acetic acid).

1.	Give important properties of ethanoic acid (Acetic acid).
Answer» Solution :Important properties of monocarboxylic ACID. 1. Ethanoic acid or acetic acid is colourless liquid and is soluble in water, 5-8% solution of acetic acid in water is called VINEGAR. 2. PURE ethanoic acid melts at 290 K and freezes during winter in cold climates and looks like ice. Hence it is called glacial acetic acid. 3. Esterification. When an acid is heated with an alcohol in the presence of conc. `H_(2)SO_(4)`, an ester is produced. Thus is a slow reversible reaction and is called esterification. e.g. `underset(("Ethanoic acid"))(CH_(3)COOH) + underset(("Ethanol"))(C_(2)H_(5)OH)` Esters are sweet-smelling substances. 4. Action with a base `underset("Acetic acid")(CH_(3)COOH) + NaOH rarr underset("Sodium acetate")(CH_(3)COONa) + H_(2)O` 5. Action with carbonates and bicarbonates. Ethanoic acid decomposes carbonates and bicarbonates producing salt, carbon dioxide and water. `2CH_(3)COOH + Na_(2)CO_(3) rarr 2CH_(3)COONa + H_(2)O + CO_(2) uarr` `CH_(3)COOH + NaHCO_(3) rarr CH_(3)COONa + H_(2)O + CO_(2) uarr`
