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)
