Chlorine is manufactured commercially by the electrolysis of aqueous sodium chloride (brine). Which other products are made in this process?
Correct answer: C. Hydrogen and sodium hydroxide
- A. Hydrochloric acid and hydrogen
- B. Hydrogen and sodium
- C. Hydrogen and sodium hydroxide
- D. Sodium and sodium hydroxide
- E. Hydrochloric acid and sodium
Explanation
Gas extraction: Chlorine can be manufactured by the electrolysis of a sodium chloride solution (brine), whichis known as the Chlor Alkali process. The production of chlorine results in the co-products of caustic soda (sodium hydroxide, NaOH) and hydrogen gas (H2).

About Biological Molecules
The chapter covers water's polarity and biological roles, carbohydrates, lipids, proteins and nucleic acids, including their monomers, bonds, structures and functions. It also distinguishes RNA from DNA and explains conjugated molecules such as glycoproteins, glycolipids and nucleoproteins, which combine organic molecules with a non-protein component.
