What do u mean by saponification? |
| Answer» Saponification is the\xa0hydrolysis\xa0of an\xa0ester\xa0under acidic or basic\xa0conditions to form an\xa0alcohol\xa0and the\xa0salt\xa0of a\xa0carboxylic acid. Saponification is commonly used to refer to the reaction of a metallic alkali (base) with a fat\xa0or\xa0oil\xa0to form\xa0soap.\xa0Example:Ethanoic acid reacts with alcohols in the presence of a conc. sulphuric acid to form esters.C2H5OH + CH3COOH → CH3COOC2H5 + H2OThe ester, on treating with a base such as NaOH is converted back to alcohol and sodium salt of carboxylic acid. The reaction is known as\xa0saponification\xa0because it is used in the manufacture of soap. CH3COOC2H5 + NaOH → C2H5OH + CH3COONa | |
