How can Sulphur be converted to sulphuric acid?

Sulphur can be converted to sulphuric acid using concentrated nitric acid.

How is the Sulphur trioxide produced converted into sulphuric acid?

contact process, modern industrial method of producing sulfuric acid; it has largely replaced the chamber, or lead-chamber, process. Sulfur dioxide and oxygen, passed over a hot catalyst, unite to form sulfur trioxide, which in turn combines with water to make sulfuric acid.

What is the process of making sulphuric acid?

In the contact process SO2 is oxidized to sulfur trioxide (SO3) at high temperature (about 450°C) in the presence of a vanadium catalyst. SO3 then is dissolved in concentrated sulfuric acid forming fuming sulfuric acid (oleum). This can then be reacted safely with water to produce concentrated sulfuric acid.

What is the Valency of sulphur in sulphuric acid?

6
In case of sulfuric acid, Sulphur atom present in it forms six covalent bonds with its neighbouring atoms i.e. with the oxygen atoms as: So, hence the valency of Sulphur in sulphuric acid is 6.

How do you make Sulphuric acid fuming?

General description. Fuming sulfuric acid is an inorganic acid, that can be produced by the addition of sulfur trioxide to concentrated sulfuric acid. It is commonly used as a sulfonating reagent in sulfonation reactions.

How is conc H2SO4 diluted?

Concentrated sulfuric acid has a very strong affinity for water. To dilute the acid, the acid should be added slowly to cold water with constant stirring to limit the buildup of heat. Sulfuric acid reacts with water to form hydrates with distinct properties.

What is Sulphur valency?

The sulphur atom has 6 electrons in the outermost shell, and its valency could be 6. But it is easier for sulphur to gain two electrons instead of losing six electrons. Hence, its valency is determined by subtracting six electrons from the octet and this gives a valency of two for sulphur.

How are Oleums formed?

Oleum is made by dissolving Sulfur Trioxide into Sulfuric Acid. Sulfur Trioxide is made from Sulfur Dioxide in the presence of a catalyst.

How do you make oleum?

Oleum is produced in the contact process, where sulfur is oxidized to sulfur trioxide which is subsequently dissolved in concentrated sulfuric acid. Sulfuric acid itself is regenerated by dilution of part of the oleum.

How do you make sulphuric acid from Sulphur?

Industrially sulphuric acid is produced from sulphur by the Contact process . 2, next sulphur dioxide is further oxidised to sulphur trioxide in the presence of vanadium pentoxide as the catalyst .

How do you convert sulphuric acid to oleum?

Sulphur or sulphide ores are burnt with excess air to produce Sulphur di-oxide. The SO2 is then converted to SO3 with excess oxygen left in the reaction mixture (preferably) on a catalytic surface. The SO3 is then absorbed into concentrated sulphuric acid to form fuming sulphuric acid or Oleum.

What is the best way to convert dioxide to sulfuric acid?

The oxidation of dioxide to sulfur trioxide and its subsequent conversion to sulfuric acid is currently almost exclusively carried out using the contact process, in particular the double contact process. The lead chamber process is no longer important.

What are the raw materials for the manufacture of sulphuric acid?

Sulphur, air or oxygen and water are the raw materials for the manufacture of sulphuric acid. The Contact process consists of three stages: (a) Sulphur is burnt in air to produce sulphur dioxide. (b) Sulphur dioxide can also be produced by burning metal sulphides such as zinc sulphide and lead sulphide.
