Saponification is a chemical reaction between a fatty acid (or fatty acid ester) and a base, such as sodium hydroxide (NaOH) or potassium hydroxide (KOH), to produce soap and glycerol (also known as glycerin). . This reaction is typically used in the production of soaps.

Here is the general equation for saponification:

Fatty acid + Base → Soap + Glycerol

Fatty acids are molecules composed primarily of a long chain of carbon atoms with a carboxyl group (-COOH) at one end. The bases used in saponification dissociate to form hydroxyl ions (OH-), which react with fatty acids to form fatty acid salts, which are soaps.

The saponification reaction is an exothermic reaction, meaning it releases heat. During saponification, fatty acids are hydrolyzed in the presence of a strong base, breaking down the esters in which they are contained and forming fatty acid salts, which are soaps, and glycerol as a byproduct.

Soaps produced by saponification are surfactants, meaning they can reduce the s
