Soap cleans things by allowing oil and water to mix. the process is called emulsification. the ch2 part of the molecule resembles oil in polarity and dissolves in the oil, while the coo- part of the molecule resembles water in polarity and attaches to water molecules. draw a picture showing 10 stearate ions immersed in a grease glob surrounded by water. use the shorthand notation for the molecule from page 91. show it with a sign taking the place of the right-hand h. the heads of the stearate ions will line the outer surface of the glob, and all of the tails will point to and almost meet in the center of the glob.
