Question:

Match Column I with Column II

Column I Column II
A. Bistered Cu 1. Aluminium
B. Blast furnace 2.  Cu2O  +  Cu2S → 6Cu  +  SO2
C. Reverberatory furnace 3. Iron
D. Hall-Heroult process 4. FeO  +  SiO2 → FeSiO3

 

Options:

A-4; B-3; C-2; D-1

A-2; B-3; C-4; D-1

A-1; B-3; C-4; D-4

A-1; B-2; C-3; D-4

Correct Answer:

A-2; B-3; C-4; D-1

Explanation:
  •  Cu2O  +  Cu2S → 6Cu  +  SO2
    The solidified copper obtained has blistered appearance due to the evolution of SO2​ and so it is called blister copper.
  • Iron is extracted from blast furnace.
  • The ore is heated in a reverberatory furnace of after mixing with silica. In the furnace, iron oxide slags of as iron silicate and copper is produced in the form of copper matte.
  • Hall-Heroult process single is used for the extraction of Al.
