Is soap a mixture?
Soap is a mixture of sodium salts of various naturally occurring fatty acids. Air bubbles added to a molten soap will decrease the density of the soap and thus it will float on water. Soap is produced by a saponification or basic hydrolysis reaction of a fat or oil.
Soaps are denoted by the general formula RCOO-Na+, where R is any long chain alkyl group consisting 12 to 18 carbon atoms. Some common examples of fatty acids that are used in soaps are stearic acid having chemical formula C17H35COOH, palmitic acid having chemical formula C15H31COOH.
