Aluminothermic process is used for the extraction of metals, whose oxides are

A

fusible

B

not easily reduced by carbon.

C

not easily reduced by hydrogen.

D

strongly basic.

Text Solution

Verified by Experts

The correct Answer is:
B
Aluminothermite process involves reduction of oxides which are not satisfactorily reduced by carbon such as `Fe_2 O_3 ,Mn_3 O_4 , Cr_2 O_3` etc. to metals with aluminium. `Cr_2 O_3 +2Al to Al_2 O_3 + 2Cr Delta H = -ve `
