Question

Alumino thermite process involves reduction of chromium with oxide and aluminium.

• A. True
• B. False

Answer 1

The correct option is A True

$F{e}_2{O}_3+2Al\to A{l}_2{O}_3+2Fe$

In Alumino thermite process the aluminium act as reducing agent. In this preocess the oxides of various metals (like chromium, iron, etc.) are converted into their corresponding metals. For example: the reduction of ferrous oxide in presence of aluminium results in the formation of ferrous metal. It is exothermic reaction.
