What is the process of alkaline hydrolysis of an ester to produce soap called?
Answer and explanation
Correct answer: Saponification
When an ester is hydrolysed with an alkali such as sodium hydroxide or potassium hydroxide, it forms the sodium or potassium salt of a carboxylic acid. Such salts formed from fats or oils are soaps. This process is called saponification. In contrast, neutralisation is the direct reaction of an acid with a base to form salt and water; it does not involve hydrolysis of an ester.
