Question

Explain how the following metals are obtained from their compounds by reduction process also write the equation
a) Metal X which is low in reactivity series
b) Metal Y which is in the middle of the reactivity series
c) Metal Z which is high in the reactivity series

Answer 1

 1. metals low in reactivity series are obtained by the method of Heating Alone
 2. metals in the middle of the reactivity series are obtained by either
     Roasting - sulphides are converted to oxides when heated in presence of              oxygen
     or        
     Calcination - carbonates are converted to oxides when heated in absence of
     oxygen
3. Electrolytic refining
 

Answer 2

a) The metals low in reactivity series are directly subjected to heating in

(b) The metals in middle of the series are first converted to their oxides and then reduced to the corresponding
