Which of the following statements is incorrect? A) Because like dissolves like, the nonpolar end of the soap molecule can dissolve greasy dirt, and the polar or ionic end of the molecule is attracted by water molecules. B) By saturating the soap solution with NaCl or KCl, the saturation products of the Na+ and K+ salts of fatty acids are exceeded, and most of the soap is precipitated, while glycerin dissolves in water. C) The alkalinity provided by HO- damages the leather, thus making it difficult to remove the dirt. D) Soaps are divided into two as hard and soft according to their consistency. Saturated and single-double-bonded fatty acids are used in soap making. Mild soap is obtained from fatty acids containing two or three double bonds.
