In the contact process for the manufacture of sulphuric acid give the equations for the conversion of sulphur trioxide to sulphuric acid.

In the manufacture of sulphuric acid by contact process give the equation for the conversion of sulphur trioxide to sulphuric acid.

In the the manufacture of sulphuric acid by the Contact process ,give the equations for the conversion of sulphur trioxide to sulphuric acid .

Anhydride of sulphuric acid is

Some bacteria obtain their energy by oxidising sulphur, producing sulphuric acid as a by-product. In the laboratory, or in industry, 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 to give sulphuric acid. Write the equation for the conversion of sulphur dioxide to sulphur trioxide. Why does this reaction supply energy?

(i) The flow chart below shows steps in the Contact process or the manufacture of sulphuric acid : (ii) Write equations for : (1) The roasting of iron pyrites. (2) Formation of sulphur trioxide from sulphur dioxide.(III) (3) Platinum was the catalyst used in the conversion of sulphur dioxide to sulphur trioxide. What is the common name of the catalyst used nowadays ? (4) Give the formula of oleum. (5) Name the substance which is added to change oleum into sulphuric acid.

Concentrated sulphuric acid is:
