Concept: The chlor-alkali process is an industrial method used to manufacture sodium hydroxide and chlorine gas by the electrolysis of brine.Explanation:The chlor-alkali process involves the electrolysis of a concentrated solution of sodium chloride, known as brine.During this process, sodium hydroxide is formed at the cathode, while chlorine gas is released at the anode.Hydrogen gas is also produced as a by-product at the cathode.The overall reaction is: 2NaCl+2H2Oelectrolysis2NaOH+Cl2+H2Sodium bicarbonate (NaHCO3) and sodium carbonate (Na2CO3) are typically produced by the Solvay process, not by the chlor-alkali process.Sodium chloride (NaCl) is the raw material used in this process, not the product formed.Thus, the chlor-alkali process directly produces sodium hydroxide and chlorine gas.Answer: The correct option is A. NaOH+Cl2.
