Question

suggest different chemical processes used for optaining a metal from its oxide for metal in the middle of the reactive series and metals toward the top of the reactivity series​

Answer 1

Answer:

1. For obtaining metals that are in the middle of the reactivity series, oxides of such metals can be reduced with coke (carbon) which acts as a reducing agent.

Example:

2 Fe2O3 + 3 C ----> 4 Fe + 3 CO2

2. For obtaining metals that are high in the reactivity series, their oxides are reduced to metals by the process of electrolysis.

Example: Electrolysis of sodium chloride

At cathode: Na+ + e- -----> Na

At anode: 2 Cl- ----> Cl2 + 2e-
