The following is an extract from 'Metals in the service of man,Alexander andStreet/ Pelican 1976':Alumina (aluminium oxide) has a very high melting point of over 2050°C so that it cannot readily be liquified. However, conversion of aluminato aluminium and oxygen, by electrolysis, can occur when it is dissolvedin some other substance".(i) Which solution is used to react with bauxite in obtaining purealumina?(ii) Write three chemical reactions involved in Bayer's process.(iii) Name the impurities associated with ore and how are theyremoved?(iv) Carbon can reduce lead oxide but not aluminium oxide. Why?(V) Name the element which serves as both the anode andcathode in the extraction of aluminium.(vi) Write the equation for the reaction that occurs at the cathodeand anode during the extraction of aluminium by clectrolysis.(vii) Name the other ore of aluminium added in electrolyte. Whyis it added(viii) Why is anode replaced from time to time?(ix) Powdered coke is sprinkled on the surface of the electrolyticmixture. Give reason.Name an alloy of Aluminium which is used to make aircraftbody and why?​
