Question

Describe the manufactured of sulphuric acid?​

Answer 1

Answer:

How Sulphuric acid is produced? Sulphuric acid is produced from sulphur. In the presence of air, sulphur dioxide is first obtained by burning the molten sulphur. In the presence of a catalyst for vanadium pentoxide, sulphur dioxide is then converted to sulphur trioxide.

Answer 2

Answer:

The starting material for sulfuric acid manufacture is clean, dry sulfur dioxide (SO2) gas. ... 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).
