Check Answer and Solution for above quest Brine is a solution of sodium chloride (NaCl) and water (H 2 O). The process of electrolysis involves using an electric current to bring about a chemical change and make new chemicals. The electrolysis of brine is a large-scale process used to manufacture chlorine from salt. Two other useful chemicals are obtained during the process, sodium hydroxide (NaOH) and hydrogen (H 2) Chlorine can be manufactured by electrolysis of a sodium chloride solution (brine). The production of chlorine results in the co-products caustic soda (Sodium hydroxide, NaOH) and hydrogen gas (H_2). These two products, as well as chlorine itself, are highly reactive. Chlorine can also be produced by the electrolysis of a solution of potassium chloride, in which case the co-products are.

Electrolysis of sodium chloride solution (brine) As shown above, the electrolysis of sodium chloride solution will produce chlorine gas at the anode and hydrogen gas at the cathode. at the anode. Chlorine extracted from the electrolysis of brine, solution. Sodium ions (Na+) are more reactive than hydrogen so remain in the solution. Extraction of bromine-uses a more reactive halogen to extract it from its brine-chlorine is more reactive than bromin

This solution is often called brine. A solution of sodium chloride contains Na + (aq) and Cl-(aq) ions and, from the dissociation of water, very low concentrations of H + (aq) and OH-(aq) ions. During the electrolysis of the solution, chlorine and hydrogen gases are produced: As the hydrogen ions are discharged, more water dissociates forming. Gas extraction Chlorine can be manufactured by the electrolysis of a sodium chloride solution (brine), which is known as the Chloralkali process. The production of chlorine results in the co-products caustic soda (sodium hydroxide, NaOH) and hydrogen gas (H 2). These two products, as well as chlorine itself, are highly reactive Chlorine gas is contaminated with oxygen that must be removed. By cooling the gas, the chlorine turns into a liquid, while the oxygen remains a gas, thus enabling its separation. This process is called liquefaction. Sodium hydroxide often contains leftover salt in the solution. The mixed sodium hydroxide and brine solution is heated to. Brine is moderately concentrated sodium chloride solution (brine) with carbon (graphite) gives equal volumes of hydrogen gas (hydrogen ions H + discharged at the -ve cathode) and green chlorine gas (chloride ions Cl - discharged at the +ve anode) with sodium hydroxide left in solution. The electrolysis will only take place when electricity. Contributors; Three important chemicals, NaOH, Cl 2, H 2, can be obtained by electrolyzing an aqueous NaCl solution (brine). This forms the basis of the chlor-alkali industry.The diaphragm cell (also called a Hooker cell) in which the electrolysis is carried out is shown schematically in Figure \(\PageIndex{1}\)

Chlorine gas extraction Chlorine can be manufactured by electrolysis of a sodium chloride solution (brine). The production of chlorine results in the co-products caustic soda (sodium hydroxide, NaOH) and hydrogen gas (H 2). These two products, as well as chlorine are highly reactive Chlorine is produced by the electrolysis of sodium chloride solution, brine. Thus, when sodium chloride is dissolved in water, it dissociates into sodium cations and chloride anions. The chloride ions are oxidized at the anode to form chlorine gas and water molecules are reduced at the cathode to form hydroxyl anions and hydrogen gas
