The anodes are blocks of carbon dipped into the electrolyte.

Applications Of Electrolysis In Industries

Reproduction of objects by electro-deposition on some sort of mould or form is known as electro-forming. Electro-Cleaning: ADVERTISEMENTS: The article to be cleaned of oil and grease is made the cathode and the iron tank or vat filled with an electrolyte solution of the electrolyte and heavy current is passed through the solution. for copper, it is copper sulphate and for nickel, it is nickel chloride.

The mould is then dipped in an electro-forming cell as a cathode.

Applications Of Electrolysis In Industries

The silver anode dissolves into the solution. At high temperature, oxygen reacts with the carbon anode to form carbon dioxide gas.

Potassium permaganate hydrogen and oxygen etc. Thus, a film of copper is formed on the prepared surface. Electro-Forming: This is another application of electro-deposition. ADVERTISEMENTS: The following table gives the information on refining of metals: Application 3. In the second process the ore is in a molten state and it is electrolysed in a furnace. Electroplating is usually done to improve the appearance of the metal or prevent the corrosion of the metal.

The surface of the wax, which bears exact impressions of the object, is coated by powdered graphite in order to make it conducting. i Extraction of Zinc: ADVERTISEMENTS: The zinc ore is treated with sulphuric acid. In the electrolytic tank, the cathodes are of aluminium and the anodes are of lead. Electro-Typing: This is a process by which type wood cuts etc.
