Question

The aluminium article is used as an anode in the anodising process. Give scientific explanation.

Answer 1

Bcz Al gives +ion bcz it is metal and anode attract +ion

Answer 2

Explanation:

Anodising is a process in which metallic surface converts into the corrosion-resistant surface.

It is done by adding aluminium into acid electrolyte and after that an electric current is applied on it.

Anodising is achieved by the controlled oxidation.Generally aluminium acts as a anode .so that the oxide ions combine with aluminium and form a layer of aluminium oxide on the metallic surface,
