Question

The following reaction takes place when aluminium powder is heated with MnO₂

`3"MnO"_2("s") + 4"Al"("s") -> 3"Mn"("l") + 2"Al"_2"O"_3("l") + "Heat"`

1. Is aluminium getting reduced?
2. Is MnO₂ getting oxidised?

Answer 1

In the given chemical reaction, aluminium is acting as a reducing agent. Aluminium is helping in the reduction of manganese dioxide to manganese and itself getting oxidised to aluminium oxide.

1. No, aluminium is getting oxidised.
2.  No, MnO₂ is getting reduced.
