What is the catalyst used to make sulfuric acid?
vanadium pentoxide catalyst
Sulphuric acid is produced from sulphur. Sulphur dioxide is first obtained by the burning of the molten sulphur in presence of air. Sulphur dioxide is then converted to sulphur trioxide in presence of vanadium pentoxide catalyst.
What is the catalyst used in the manufacture of H2SO4 by contact process?
Platinised asbestos is used as a catalyst in the manufacture of H2SO4 by contact process.
Why is 450 degrees used in the contact process?
A temperature of 450 oC is used in this reaction. This is because the reaction is exothermic such that a low temperature would favour the forward reaction and produce more sulphur trioxide. However, a low temperature slows down the rate of the reaction. Thus a compromise temperature of 450 oC is used.
How is sulphuric acid made?
Sulfuric acid is prepared industrially by the reaction of water with sulfur trioxide (see sulfur oxide), which in turn is made by chemical combination of sulfur dioxide and oxygen either by the contact process or the chamber process.
How is sulphuric acid prepared by contact?
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.
Which of the following gas is dissolved in H2SO4 to give Oleum?
Oleum is produced in the contact process, where sulfur is oxidized to sulfur trioxide which is subsequently dissolved in concentrated sulfuric acid.
Which of the following is the product when copper react with conc H2SO4?
Copper reacts with hot and concentrated sulphuric acid to form copper sulphate, sulphur dioxide gas and water.
Why is 200 ATM used in Haber process?
If the pressure is increased, the equilibrium position moves in the direction of the fewest molecules of gas. This means it moves to the right in the Haber process. Stronger equipment is needed, and more energy is needed to compress the gases. So a compromise pressure of 200 atmospheres is chosen.
Why is sulphuric acid called King of chemicals?
Sulphuric acid is called “king of acids” because of its direct and indirect applications in the manufacture of many chemicals including fertilizers. Sulphuric acid is used to clean up rust from steel rolls and soap. It also dissolves its compounds. Thus, it is ideal to call sulphuric acid as king of chemicals.
How do you handle sulphuric acid?
Ingestion – If you ingest sulfuric acid, rinse your mouth immediately with water. Do not induce vomiting. Continually rinse your mouth with water and seek medical attention as soon as possible. Inhalation – If you inhale sulfuric acid aerosols, seek fresh air and medical attention immediately.
How is Sulphuric acid prepared from 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.
