In Gold Schmidt reaction, certain metallic oxides are reduced to the metallic state by heating with

A

metallic magnesium

B

metallic aluminium

C

metallic iron

D

sodium metal

Text Solution

Verified by Experts

The correct Answer is:
B
Aluminium is reducing in nature. The reduction of `Fe_(2)O_(3)` by Al is known as Gold Schmidt aluminothermic process
`2Al+Fe_(2)O_(3) rarr Al_(2)O_(3)+2Fe Delta H =-ve` (exothermic)
