Chemicals from NaCl: 1 : VIDEO/DVD, Because of its wide availability, NaCl is the starting material for many inorganic chemicals. In this program, salt is seen being pumped to the surface from deposits of 1011 tons in salt fields as a brine solution, and into a chemical plant where chlorine and sodium hydroxide are produced by electrolysis. Three types of cells used to separate the products at the anode and cathode—mercury cathode, diaphragm, and membrane—are shown and the commercial advantages and disadvantages of each are presented for discussion.
