Give two balanced reactions of each type to show the following properties of sulphurric acid :
(a) Acidic nature, (b)Oxidising agent,
(c) Dehydrating nature, (d) Non- volatile nature.
(a) Name the process used for the large scale manufacture of sulphuric acid. (b) Which property of sulphuric acid accounts for its use as a dehydrating agent? (c) Concentrated sulphuric acid is both an oxidising agent and a non-volatile acid. Write one equation each to illustrate the properties of sulphuric acid mentioned above.
Describe the reactions that show (i) Concentrated sulphuric acid is a non-volatile acid. (ii) Concentrated sulphuric acid acts as a dehydrating agent. (iii) Concentrated sulphuric acid is an oxidising agent. (iv) Dilute sulphuric acid behaves as dibasic acid.
