Detailed explanation-1: -The products of a saponification reaction are soap and glycerol. Soaps are water-soluble sodium or potassium salts of fatty acids. They can be produced from fats called triglycerides by reacting them with a strong alkali.

Detailed explanation-2: -Saponification is a process by which triglycerides are reacted with sodium or potassium hydroxide (lye) to produce glycerol and a fatty acid salt called “soap.” The triglycerides are most often animal fats or vegetable oils. When sodium hydroxide is used, a hard soap is produced.

Detailed explanation-3: -Soap is a sodium or potassium salt of fatty acids which have cleansing property in water. ∙ Sodium soaps are called hard soaps and potassium salts are called soft soaps. ∙ Hard soap is moderately soluble in water and does not produce lather easily. Whereas, soft soap dissolves faster and produces lather readily.
