Which of the following gases acts as a reducing agent?
Oxygen
Sulphur dioxide
Sulphur trioxide
None of the above
Name the catalyst used to convert sulphur dioxide to sulphur trioxide
Some bacteria obtained their energy by oxidising sulphur, producing sulphuric acid as a by-product. In the laboratory or industrially, the first step in the conversion of sulphur to sulphuric acid is to produce sulphur dioxide. The sulphur dioxide is converted to sulphur trioxide, which reacts with water producing sulphuric acid.
(a) Name one catalyst used industrially, which speeds up the conversion of sulphur dioxide to sulphur trioxide.
(b) Write the equation for the conversion of sulphur dioxide to sulphur trioxide. Why does this reaction supply energy?
(c) What is the name of the compound formed between sulphuric acid and sulphur trioxide?
Name the catalyst which helps in the conversion of sulphur dioxide to sulphur trioxide?
