What is Aluminium?
Aluminium is a soft, silvery-white, ductile, nonmagnetic metal in the boron group.
It is the third most abundant element in the Earth’s crust. Depending on the surface reference, aluminium appears in the range from silvery to dull grey.
Uses of Aluminium
- It is used in the transportation of railway, trucks, automobiles as castings.
- It is used in packaging.
- Al(II) compounds are observed in the reactions of Al metal with oxidants.
- Using aluminon the presence of aluminium can be detected in qualitative analysis.
