Why is many cooking pan made of aluminum although it is a reactive metal?

Aluminum can be treated by anodization to create an inert hard protective layer over the surface. This layer can be either transparent or by the addition of tiny amounts of dopant elements during the process a wide range of colorscan be produced.
Even without anodization, a bare aluminum surface is so reactive that a layer of transparent aluminum oxide rapidly builds preventing further reaction.
But do not use aluminum utensils with acidic foods or scrub with abrasives when cleaning, this will remove anodization or the natural oxide protection leaving the bare reactive metal again.

∙ 11y agoAluminium has a very thin layer of its oxides on the surface so it can stop air/water getting to the metal.
It is an resistant to corrosion (AKA Rust)
Wiki User
∙ 12y agoAluminium does not corrode easily. Even if it corrodes it reacts with oxygen to form a layer of aluminium oxide around it, which protects it from further corrosion.

∙ 10y agobecause aluminium has great affinity for oxygen and so there is a shining coating of aluminium oxide on the foil which is stable

Does magnesium react with aluminium sulphate?
No.Mg is less reactive than aluminum,therefore mg solution will not react with aluminum metal.
Which metal is most reactive between copper and aluminium?
aluminum
Which metal will replace aluminum in a solution of aluminum compound?
Any metal which is more reactive than Aluminium, for example any metal in group 1 or 2.
Why you use aluminum foil as aluminum is reactive metal?
Aluminium oxidises when it comes in contact with the air and creates a protective coat on itself.
Why does aluminium has low reactivity in the reactivity series?
Aluminum is exactly as reactive as it is in the reactivity series. However, when aluminum reacts, with oxygen for instance, a thin layer of aluminum oxide builds up on the outside of the aluminum metal. This prevents more oxygen from reaching unreacted aluminum metal. This prevents the reaction from proceeding further, thus effectively protecting the aluminum metal from further reaction.
Is magnalite cookware considered reactive?
This type of cookware is made of aluminum which is a reactive and soft metal. During cooking, the aluminum can leech to the food being prepared.
Is aluminium a most reactive metal?
Aluminum is pretty reactive, but it is nowhere near the most reactive.
Does magnesium react with aluminium sulphate?
No.Mg is less reactive than aluminum,therefore mg solution will not react with aluminum metal.
Which metal is most reactive between copper and aluminium?
aluminum
What is the difference between sodium and aluminum'?
Sodium is a highly reactive alkali metal whereas aluminium is a less reactive metal in the boron group.
Which is the most reactive titanium aluminum or platinum?
Aluminium and titanium are about the same but aluminium is more reactive. platinum is the least reactive metal
Which metal will replace aluminum in a solution of aluminum compound?
Any metal which is more reactive than Aluminium, for example any metal in group 1 or 2.
What element potassium iron or aluminum is most reactive?
Potassium is the most reactive. It is in the 1st group. It is an alkaline metal.
What element from potassium iron or aluminum is most reactive?
Potassium is the most reactive. It is in the 1st group. It is an alkaline metal.
Why is aluminum often unreactive to acid?
Actually, aluminum is very reactive. It is so reactive that it forms thin layers of oxide on its surface at room temperature. This thin film protects the metal underneath from further oxidation. Some aluminum parts are " nitrided" for even better protection. This is very popular with tools and cooking pans.
Is aluminum a metal nonmetal or a metalloid?
It can be considered a metalloid, although it is commonly regarded as a metal.
What happens if you put copper metal into a solution of aluminum sulfate?
Nothing will happen. Displacement reaction only happens when the element is more reactive than the salt solution. An example will be the otherwise. If you put aluminum metal into a solution of Copper (II) Sulfate. The aluminum metal will displace copper metal and you will have a solution of Aluminum Sulfate and copper metal. As long the element you put into the salt solution is more reactive than the cation of the solution, it will displace the metal.
