Question

What kind of solution is rusted iron , Solid in gas or gas in solid???? Explain your answer.

Answer 1

Answer:

The main catalyst for the rusting process is water. Iron or steel structures might appear to be solid, but water molecules can penetrate the microscopic pits and cracks in any exposed metal.

Answer 2

Answer :-

When iron is in contact with water and oxygen it rusts. If salt is present,

for example in seawater or salt spray, the iron tends to rust more quickly, as

a result of electrochemical reactions. Iron metal is relatively unaffected by

pure water or by dry oxygen. As with other metals, like aluminum, a tightly

adhering oxide coating, a passivation layer, protects the bulk iron from

further oxidation. The conversion of the passivating ferrous oxide layer to

rust results from the combined action of two agents, usually oxygen and

water.

Other degrading solutions are sulfur dioxide in water and carbon dioxide in

water. Under these corrosive conditions, iron hydroxide species are

formed. Unlike ferrous oxides, the hydroxides do not adhere to the bulk

metal. As they form and flake off from the surface, fresh iron is exposed,

and the corrosion process continues until either all of the iron is consumed

or all of the oxygen, water, carbon dioxide, or sulfur dioxide in the system

are removed or consumed.

When iron rusts, the oxides take up more volume than the original metal;

this expansion can generate enormous forces, damaging structures made

with iron.

Rust solution do not form any type of sol or colloid. So, it is neither Solid in

gas, nor gas in solid. In, fact it is a chemical product obtained by corrosion

of iron.
