Respuesta :
The material which is used as source for commercial production of chlorine is salt (sodium or potassium chloride).
Most chlorine is manufactured by the electrolysis through mercury cell process. In the process, a salt solution (sodium or potassium chloride) is electrolyzed by the action of direct passing of electric current from the solution which converts chloride ions to elemental chlorine.
Chlorine is also produced by many ways, for instance, by the electrolysis of molten sodium or magnesium chloride to make elemental magnesium or sodium metal; by the electrolysis of strong hydrochloric acid; and even by the non-electrolytic processes.
What is mercury cell technology?
Mercury Cell technology include the uses of stream of mercury which is flowing as the cathode along the bottom of the electrolyzer. The anodes are suspended in such a way that it is parallel to the base of the cell which is few millimeters above the flowing mercury. Brine is fed in one end of the cell box and flows through the gravity between the cathode and the anode. Chlorine gas is evolved and then released at the anode.
On the other side sodium ions are deposited at the cathode along the surface of the flowing mercury. The alkali metal which dissolves in the mercury, start forming a liquid amalgam. The amalgam formed flows by gravity from the electrolyzer towards the carbon-filled decomposer, where the deionized water is added. The process continued and Mercury is collected for further process.
Thus, we concluded that the material which is used as source for commercial production of chlorine is salt (sodium or potassium chloride).
