Galvanisation is a method of protecting steel and iron from rusting by coating them with a thin layer of zinc. The zinc coating acts as a sacrificial anode, corroding preferentially to the iron or steel substrate. Even if the zinc ...

The rusting of iron can be prevented by various methods including painting, oiling, greasing, galvanising, chrome plating, anodising, or making alloys.

The thin strip of pure metal serves as the cathode to ensure that only pure metal is deposited during the electrolytic refining process, resulting in the production of high-quality, refined metal.

During electrolytic refining, soluble impurities dissolve into the electrolyte, while insoluble impurities settle at the bottom of the anode as anode mud.

In electrolytic refining, the impure metal is made the anode, while a thin strip of pure metal is made the cathode. A solution of the metal salt serves as the electrolyte. When a current is passed through the electrolyte, the ...
