Hint :Aluminium is a chemical element with the atomic number 13 and the symbol Al. Aluminium has a lower density than most other common metals, around one-third that of steel. When exposed to sunlight, it has a strong affinity for oxygen and forms a protective layer of oxide on the surface.

Aluminium is a chemical element with the atomic number 13 and the symbol Al. Aluminium has a lower density than most other common metals, around one-third that of steel. When exposed to sunlight, it has a strong affinity for oxygen and forms a protective layer of oxide on the surface.
When pure, sulfuric acid is a solid mineral acid that is colourless. This substance is used as a chemical intermediate in the production of other chemicals as well as for cleaning metal surfaces. H₂SO₄ is the chemical formula for sulfuric acid.
With the release of sulphur dioxide gas, aluminium reacts with heavy, concentrated sulphuric acid to form aluminium sulphate. Sulphuric acid is an oxidising agent that reduces itself to SO₂. Only in dilute acid does the metal release hydrogen gas.
$ 2Al + 3{H_2}S{O_{4}} \to A{l_2}{(S{O_4})_3} + 3{H_{2}} $
Aluminium sulphate has the formula Al₂(SO₄)₃. It is soluble in water and is primarily used as a coagulating agent (a neutralising charge that promotes particle collision) in the purification of drinking water and wastewater treatment plants, as well as in the production of paper.
Note :
The chemical element hydrogen has the symbol H and the atomic number 1. Hydrogen is the lightest element in the periodic table, with an atomic weight of 1.008. Hydrogen is the most common chemical element in the world, accounting for around 75% of all baryonic mass.
