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 (H2). These two products, as well as chlorine itself, are highly reactive.
Keeping this in consideration, how is sodium hydroxide produced?
Sodium hydroxide is produced (along with chlorine and hydrogen) via the chloralkali process. This involves the electrolysis of an aqueous solution of sodium chloride. The sodium hydroxide builds up at the cathode, where water is reduced to hydrogen gas and hydroxide ion: 2Na+ + 2H2O + 2e− → H2 + 2NaOH.
Also Know, how is chlorine prepared commercially? Commercially, chlorine is prepared by the electrolysis of aqueous sodium chloride obtained from seawater or salt deposits. Another process for the production of chlorine is the Chloralkali Process.
Herein, why is chlorine produced at the anode?
At the anode Two chloride ions each give up an electron to the anode, and the atoms produced combine to give chlorine gas. The chlorine is, however, contaminated with small amounts of oxygen because of a reaction involving hydroxide ions giving up electrons as well.
Why is sodium hydroxide formed at the cathode?
H2(g) and NaOH(aq) are produced at the cathode (negative electrode). As the hydrogen ions are converted into hydrogen gas, the water equilibrium tips to the right to replace them. Equilibrium shifts to produce more hydroxide ions as H+ ions are removed during hydrolysis.
