question 17

Multiple Choice

Soap is an anionic surfactant used in conjunction with water for washing and cleaning. It is a typical example for European Medieval technology. Animal or plant fats are hydrolyzed by the strong base (NaOH in water, usually called lye) , yielding alkali salts of fatty acids and glycerol. Historically, tallow (beef or mutton fat) is used for saponification. Tallow contains glycerol esters of oleic acid (47%) , palmitic acid (26%) and stearic acid (14%) . What are the chemical components of soap from tallow? Soap is an anionic surfactant used in conjunction with water for washing and cleaning. It is a typical example for European Medieval technology.
