Write a balanced chemical equation for the following:
Action of concentrated sulphuric acid on Sulphur.
Write balanced chemical equations for the action of dilute sulphuric acid on sodium sulphite.
Give two balanced reactions of the type to show the following property of sulphuric acid:
Oxidising agent
Define the following term : Dehydrating agent
Describe the reaction that show
Concentrated sulphuric acid is a non-volatile acid.
Give examples of the use of sulphuric acid as
An oxidizing agent
- Name the catalyst which helps in the conversion of sulphur dioxide to sulphur trioxide in step C.
- In the contact process for the manufacture of sulphuric acid, sulphur trioxide is not converted to sulphuric acid by reacting it with water. Instead a two-step procedure is used. Write the equations for the two steps involved in D.
- What type of substance will liberate sulphur dioxide from sodium sulphite in step E?
- Write the equation for the reaction by which sulphur dioxide is converted to sodium sulphite in step F.

A. Dilute acid (typical acid properties)
B. Non-volatile acid
C. Oxidizing agent
D. Dehydrating agent
(i) Preparation of hydrogen chloride.
(ii) Preparation of ethane from ethanol
(iii) Preparation of copper sulphate from copper oxide.
What property of sulphuric acid is shown by the reaction of concentrated sulphuric acid when heated with :
(i) Potassium nitrate
(ii) carbon
