What would you observe when zinc is added to a solution of iron(II) sulphate? Write the chemical reaction that takes place. 

 

ANS.

When Zinc is added to a solution of Iron (II) sulphate, a displacement reaction takes place. 

  • Zinc being a more reactive metal than Iron (as zinc lies about iron in the reactivity series), will replace iron from its salt solution.
  • The reaction produces Zinc sulphate + Iron. 
  • The Iron settles as a grey precipitate and a colourless solution of zinc is formed.
  • The reaction can be given as,

FeSO 4 (aq) + Zn (s) → ZnSO 4 (aq) + Fe (s)
