Question

What are the products for the following reactions
1. Iron (II) + Copper chloride → ________ + _
2. Sodium + Zinc chloride → __ + _
3. Potassium + Aluminium chloride → __ + _
4. Zinc + Copper chloride → __ + _
5. Mercury + Copper chloride → + _____

Open in App

Solution

Dear student,
1. Fe + CuCl₂ → Cu + FeCl₂ (Copper + Iron(ii)Chloride)
2. 2Na + ZnCl₂ → 2NaCl + Zn (Sodium Chloride + Zinc)
3. 3K + AlCl₃ → 3KCl + Al (Potassium Chloride + Aluminium)
4. Zn + CuCl₂ → ZnCl₂ + Cu (Zinc Chloride + Copper)
5. Hg + CuCl₂ → No Reaction (Because Hg is less reactive metal than Cu and hence cannot replace it from its compound)
