The mass of carbon anode consumed (giving only carbon dioxide) in the production of `270 kg` of aluminium metal from bauxite by the Hall process is

A

180kg

B

270kg

C

540 kg

D

90kg

Text Solution

Verified by Experts

The correct Answer is:
D
`(omega_(1))/(E_(1))=(omega_(2))/(E_(2)),(omega_(1))/(3)=(270)/(93),omega_(1)=90kg`

    Why is it necessary to replace carbon anode from time to time in the electrolytic extraction of aluminium ?

    Since coal and petroleum have been formed from bio-mass, in addition to carbon, these contain hydrogen, nitrogen and sulphur. When these are burnt, the products are carbon dioxide, water, oxides of nitrogen and oxides of sulphur. When combustion takes place in insufficient air (oxygen), then carbon monoxide is formed instead of carbon dioxide. Of these products, the oxides of sulphur and nitrogen and carbon monoxide are poisonous at high concentrations and carbon dioxide is a greenhouse gas. Another way of looking at coal and petroleum is that they are huge reservoirs of carbon and if all of this carbon is converted to carbon dioxide, then the amount of carbon dioxide in the atmosphere is going to increase, leading to intense global warming. Thus, we need to use these resources judiciously. What is the common source of carbon dioxide, water, oxides of nitrogen and suplhur in the air ?
