Topic 2.5: Industrial inorganic chemistry

return to AS and A2 chemistry

You should be able to:
2.5a recall the conditions used in the manufacture of ammonia by the Haber Process and its conversion to nitric acid
· recall of technical details of the plant will not be required)
2.5b recall the conditions used in the manufacture of sulphuric acid by the Contact Process
· recall of technical details of the plant will not be required)
2.5c apply the knowledge gained in this unit concerning enthalpy change, equilibria and kinetics to justify the conditions used to obtain an economic yield in the processes in (a) and (b)
2.5d recall the use of ammonia, nitric acid and sulphuric acid to include the manufacture of inorganic fertilisers
2.5e recall and explain the electrolytic extraction of aluminium from purified bauxite and the fact that it is economically important yet expensive
· the outline of the purification of bauxite is required but equations involving the aluminate ion will not be examined in this unit)
· include the importance of the recycling of aluminium)
2.5f recall the uses of aluminium and relate these to the properties of the metal.

2.5g recall the production of chlorine and sodium chlorate(I) by the electrolysis of sodium
chloride solution
· only outline details of the industrial plant will be required. However, students will be expected to recall the equations for the reactions at the electrodes and the overall equations for the process occurring in the membrane cell
2.5h recall the uses of chlorine and sodium chlorate(I).
