Question

In the alumino-thermic process, Aluminium acts as

• A. An oxidising agent
• B. A flux
• C. A reducing agent
• D. A solder

Answer 1

The correct option is C

A reducing agent

Aluminothermic reactions are high-temperature exothermic chemical processes that use Aluminium ($Al$) as a reducing agent. The procedure may be used to make Iron ($Fe$) alloys in the industrial environment.

For example, the thermite reaction, which produces Iron ($Fe$) from Iron oxides ($F{e}_2{O}_3$) and Aluminium ($Al$).

Explanation for correct option:

(C) A reducing agent

In the alumino-thermic process, Aluminium ($Al$) acts as a reducing agent as it gets oxidized.

The equation for oxidation is

$\underset{Aluminimum}{2Al\left(s\right)}+\underset{Ironoxide}{F{e}_2{O}_3\left(s\right)}\to \underset{Iron}{2Fe\left(molten\right)}+\underset{Aluminiumoxide}{A{l}_2{O}_3\left(s\right)}$

Hence, the correct option is (C).
