WEBGeneral Equation for Saponification. During saponification, esters are cleaved in the presence of aqueous alkali to form an alcohol and an alkali-metal salt of carboxylic acid. The alkali used in this process is sodium hydroxide (NaOH) or lye for hard soap and potassium hydroxide (KOH) for soft soap.

WEBJan 23, 2023 · Saponification. Page ID. Esters can be cleaved back into a carboxylic acid and an alcohol by reaction with water and a base. The reaction is called a saponification from the Latin sapo which means soap. The name comes from the fact that soap used to be made by the ester hydrolysis of fats. koh

WEBSaponification is a process involving the hydrolysis of fats on its reaction with alkali, thereby leading to the formation of salts of fatty acids and glycerol. The salts of fatty acids are known as soap. The amount of potassium hydroxide required in the hydrolysis indicates the saponification value of fat.
