Question
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 KCI, 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.
The alkalinity provided by C. HO- damages the leather, making it difficult to
remove 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.
