Question

Explain how the following metals are obtained from their compounds by the reduction process.

1) metal X which is low in the reactivity series

2) metal Y which is the middle of the reactivity series

3) metal Z which is high in the reactivity series

.Give an eg of each

Answer 1

Metal x by thermal decomposition
2hg on heating gives 2hg+o2
Metal y by reducing by reducing agents
Cuo+Co gives cu+co2
Metal z by electrolysis
Mgo gives mg2+ and o2-
