'''Producing soap''' is done through a chemical reaction called ''saponification ,'' in which a fat reacts with a strong base to form soap and glycerol. The reaction involves a nucleophilic attack by hydroxide ions on the ester bond of a triglyceride (fat) into glycerol and salts of fatty acids (soap). | |||
