Write the method of preparation of carboxylic acid compounds from ester compounds,with suitable examples.

(N/A) $(i)$ Acidic hydrolysis of esters gives directly carboxylic acids while basic hydrolysis gives carboxylates,which on acidification give corresponding carboxylic acids.
$(ii)$ General reaction:
$R-CO-OR' + H_2O \xrightarrow{H^+} RCOOH + R'OH$
$(iii)$ Examples:
Example-$(i)$:
$C_6H_5COOC_2H_5 + H_2O \xrightarrow{H_3O^+} C_6H_5COOH + C_2H_5OH$
(Ethyl benzoate $\rightarrow$ Benzoic acid + Ethanol)
Example-$(ii)$:
$CH_3COOC_2H_5 + H_2O \xrightarrow{H_3O^+} CH_3COOH + C_2H_5OH$
(Ethyl acetate $\rightarrow$ Ethanoic acid + Ethanol)
