In one industrial process that uses this technique, calcium chloride is added to rock salt to decrease itsmelting point.
In one industrial process that uses this technique, calcium chloride is added to rock salt to decrease itsmelting point. Aqueous chlorine gas cannot be produced by this process because oxygen is preferentiallyoxidized. This process is governed by a law stating that the amount of product is proportional to the amountof electrons supplied. This technique is used in the Downs process to make sodium, and in platingchromium metal surfaces. For 10 points, name this process governed by Faraday's law, in which a redoxreaction separates pure compounds from an ionic substance and drives a reaction that would normally notbe spontaneous.
