EXPERIMENT NO. 6 PREPARATION AND PROPERTIES OF SOAP POST-LAB Soaps are any metallic salt of higher fatty acids. They are produced by the saponification of fats & soaps by hydrolyzing oil in the presence of a strong base. Soap is the alkali metal salts of fatty acids while the base is called the saponifying agent. Therefore, in oils, it is the fatty acid that is converted into soap.
