How can a layer of aluminum oxide be made thicker and what is the process called?
The layer can 't thickned further because Al2O3 aluminium oxide or in other words corrosion. IT is the tendency of aluminium that the layer of aluminium oxide(white in colour) or corrosion prevents the metal from further corrosion.So only one layer of aluminium oxide can be on the meatal it cant be thickned.
What is metal cladding?
It is the process in which thin layer of coating metal get bonded to base metal one or both sides permanently when they are passed through heavy rollers under the action of heat and pressure.. e.g. Aluminium-clad sheets are used in aircraft which is prepared by sandwitching duralumin sheet between two layer of pure aluminium
Why aluminium resistant to corrosion?
Aluminum is resistant to corrosion due to a thin oxide layer that forms on its surface when exposed to air. This oxide layer acts as a protective barrier, preventing further oxidation and corrosion of the metal. Additionally, aluminum's reactivity with oxygen is relatively low compared to other metals, making it more resistant to corrosion.
Why is aluminium can be used outdoors even though it is quiet high in the reactivity series?
Aluminium forms a thin, protective oxide layer on its surface when exposed to oxygen, which helps prevent further corrosion. This oxide layer makes aluminium highly resistant to corrosion, allowing it to be used outdoors even though it is high in the reactivity series.
Why does aluminium lose its shine when exposed to air?
Aluminum forms a thin layer of aluminum oxide when exposed to air, which is dull in appearance and not as reflective as pure aluminum. This oxide layer protects the aluminum from further corrosion, but it also contributes to the loss of shine.

What can you do to thicken the ozone layer?
The ozone layer protects us from the harmful UV rays of the sun. To thicken it, we must ban CFC's.
Why aluminium is passive toward concentrated nitric acid?
Because when aluminium comes into contact with nitric acid, an impervious layer ofaluminium oxide is formed. This layer of aluminium oxide will prevent the nitric acid from coming into contact with the inner aluminium metal. Thus this layer protect and prevent further reaction.
What are the products of rusting aluminum?
Not rusting of aluminium; a protective layer of aluminium oxide is formed.
What kind of metal is an OPC drum from a toner cartridge made of?
OPc drum is a 3 (three) chemical coated roler of aluminium. 1st layer is called UCL, 2nd layer called CGL (composition of CGM & CGB) and 3rd layer is CTL (Composition of CTM & CTB).
Does aluminum foil corrode if left outside?
Aluminum foil can corrode over time when exposed to outdoor elements like moisture, salt, and acids in the air. This can cause the foil to become discolored or develop spots. To prevent corrosion, store aluminum foil in a cool, dry place when not in use.
Why Al is neither attacked by dilute sulphuric acid nor dilute nitric acid?
A protective layer is formed at the surface of aluminium; the phenomenon is called passivation.
What is is the chemical coating which stops aliminum form corroding?
Aluminium has a natural coating of Aluminium oxide that prevents it from oxidizing (corroding). This layer forms as soon as the Aluminium is made and is impervious to oxygen and water and prevents further oxididation. Some acids and bases can dissolve this layer and then the Aluminum will corrode.

Why does an aluminium vessel loose its shine soon after use?
Oxidation of aluminum, formation of a thin layer of aluminum oxide.
What is it called when plants shed leaves they form a losse layer called?
The process of shedding leaves is called abscission, and the layer that forms at the base of the leaf stem, facilitating its detachment, is known as the abscission layer.
What is the equation for a piece of aluminum is added to a solution of sodium chloride?
Sodium chloride solution is corrossive for aluminium; first a layer of of aluminium oxide is formed.
