Question

SO3 is manufactured on a huge scale
by​

Answer 1

Answer:

sulphur trioxide, SO3 is commercially produced on massive scale for use in manufacturing. it is also produced as aby product of burning fossil fuels and is an air pollutant involved in the formation of acid

Answer 2

SO3 is manufactured industrially as a precursor of sulphuric acid on a huge scale by ​contact process.

Explanation:

• Sulfur dioxide is produced by burning iron pyrite or sulfur.
• Pyrite is a sulfide ore of iron.
• the ore is purified by electrostatic precipitation, here $SO2$ is oxidized by the atmospheric oxygen  $400 to 600 °C$ in the presence of a catalyst.
• Sulfur trioxide is commercially manufactured on a massive scale.
• It is also obtained as a by-product of the burning of fossil fuels.
• it is an air pollutant that is involved in acid rain.
• Sulfur trioxide exists in many form crystalline trimer and gaseous monomer
