Question

short note on prevention of corrosion ?​

Answer 1

Answer:

Regularly paint and oil the surface. Make sure it is kept in a dry place where moisture is absent. Wash it rarely with water (if need) and immediately dry it with a towel.

Answer 2

$\mathtt{\large{\bf{\underline{\red{Answer :- }}}}}$

Corrosion means damaging of metals. It causes enotmous danger to the metals & rust them. It coats the surface of metallic oxide or other salt on a metal. Electrons released at anodic spot move through the metal and go to another spot on the metal and reduce oxygen in presence ol H which is believed to be available from H,Co, formed due to dissolution of carbon dioxide from air into water.Hydrogen ion in water may also be available due to dissolution of other acidic oxides from the Anode.

Reaction :- 2 Fe (s) ➝ 2 Fe + 4e

The ferrous ions are further oxidised by atmospheric oxygen to ferric ions which come out as rust in the form of hydrated Ferric Oxide(Fe,O XH,o) and with further production of hydrogen ions.
