Question

Chemical reaction taking place in isolation of zinc from zinc blende

Answer 1

Write chemical reactions taking place in the extraction of zinc from zinc blende. ... In this process, impure zinc is made the anode while a pure copper strip is made the cathode. The electrolyte used is an acidified solution of zinc sulphate (ZnSO4).

Answer 2

chemical formula of zinc blende is ZnS

to obtain zinc first oxidation is used

ZnS + 2O2 = ZnO + SO3

the reduction is done

ZnO + H2 = Zn + H2O

hence, zinc is obtained
