✓
Answer
When ester treated with an alkali, the reaction gives ethanol and sodium ethanoate. This reaction is called saponification reaction because this reaction forms the basis of preparation of soap. This can be given by following equation.
$CH _3 COOC _2 H _5+ NaOH \rightarrow CH _3 COONa + C _2 H _5 OH$
$CH _3 COOC _2 H _5+ NaOH \rightarrow CH _3 COONa + C _2 H _5 OH$
