1.	What property of conc. H2SO4 is made use of in each of the following cases ? Give an equation for the reaction in each case : (a) in the production of HCI gas when it reacts with a chloride, (b) in the preparation of CO from HCOOH, (c) as a source of hydrogen by diluting it ans adding a strip of magnesium, (d) in the preparation of sulphuric acid by warming a mixture of conc.sulphuric acid and copper-turnings, (e) hydrogen sulphide gas is passed through concentrated sulphuric acid.
