    2020-7-7  Gold electrolysis. Gold electrolysis is the second, good method used in gold-making industries to separate gold from the other metals. This procedure has been noted to produce gold that is almost 99.999% pure. The principle and equipment for gold electrolysis. Gold electrolysis was invented by Emil Wholwill in 1874.

  • Electrolysis - Chemistry LibreTexts

    Electrolysis is the use of an electric current through an electrolyte to create a non-spontaneous chemical reaction. Unlike the voltaic cell, the electrolytic cell uses electric energy for a non-spontaneous reaction instead of a spontaneous reaction. The cathodes and anodes are reversed from each other.

    The Electrolysis of Aqueous Sodium Chloride. The electrolysis of aqueous sodium chloride is the more common example of electrolysis because more than one species can be oxidized and reduced. Considering the anode first, the possible reactions are (i) 2Cl − (aq) Cl 2 (g) + 2e − E ∘ anode = +1.35827 V
