Answer 1

Practical : ↓

• AIM :  To observe the actions of Zn, Fe, Cu and Al metals with above said salt solutions.

• Theory : The higher the place in reactivity series, It will displace the metals with lower place in reactivity series. (Displacement Reactions Occur).

• Materials Required : Zinc Metal Strip, Iron Metal Strip, Copper Metal Strip, Aluminium Metal Strip, $ZnSO_{4}$ Solution, $FeSO_{4}$ Solution, $CuSO_{4}$ Solution, $Al_{2}(SO_{4})_{3}$ Solution, 4 100 mL beakers, Foreceps.

Procedure :

• Add 20ml of solution of $ZnSO_{4}$ Solution, $FeSO_{4}$ Solution, $CuSO_{4}$ Solution, $Al_{2}(SO_{4})_{3}$ Solution.
• Take a strip of clean Zinc metal and cut it into small pieces.
• Add two pieces into each beaker containing $FeSO_{4}$ Solution, $CuSO_{4}$ Solution, $Al_{2}(SO_{4})_{3}$ Solution.
• Keep the beakers undisturbed.
• Note the change in colour of solutions, appearance of metal surface or any other change.
• Repeat the similar procedure by adding :

1. Copper strips to $ZnSO_{4}$ Solution, $FeSO_{4}$ Solution,$Al_{2}(SO_{4})_{3}$ Solution.
2. Aluminium strips to $ZnSO_{4}$ Solution, $FeSO_{4}$ Solution, $CuSO_{4}$ Solution.
3. Iron strips to $ZnSO_{4}$ Solution,$CuSO_{4}$ Solution, $Al_{2}(SO_{4})_{3}$ Solution.

• Observations :

Metal Zinc :

• Zinc. (Added to $CuSO_{4}$ Solution.)

1. Blue color of $CuSO_{4}$ disappears and red-brown copper particles settle down
2. {Inference} Zn can displace Cu from $CuSO_{4}$ solution$Zn\:+\:CuSO_{4}\implies\:ZnSO_{4}\:+\:Cu$

• Zinc. (Added to $Al_{2}(SO_{4})_3$ Solution.)

1. Solution remains colorless. (No Change.)
2. {Inference}Zn cannot displace Al from $Al_2(SO_{4})_{3}$ solution.

• Zinc. (Added to $FeSO_{4}$ Solution.)

1. Green colour of ferrous sulphate disappears. Iron metal is settles down.
2. {Inference} Zn can displace Fe from FeSO4 solution. $Zn\:+\:FeSO_{4}\implies\:ZnSO_{4}\:+\:Fe$

Metal Copper :

• Copper (Added to $FeSO_{4}$ Solution.)

1. Solution remains colorless.
2. {Inference} Cu cannot displace Fe from $FeSO_{4}$ solution.

• Copper (Added to $ZnSO_{4}$ Solution.)

1. Solution remains colorless.
2. {Inference} Cu cannot displace Zn from $ZnSO_{4}$ solution.

• Copper (Added to $Al_{2}(SO_{4})_{3}$ Solution.)

1. Solution remains colorless.
2. {Inference} Cu cannot displace Zn from $Al_{2}(SO_{4})_{3}$ solution.

Metal Aluminium :

• Aluminium (Added to $FeSO_{4}$ Solution.)

1. Iron metal is settles down
2. {Inference} Al can displace Fe from $FeSO_{4}$ solution.  $2Al + 3FeSO_{4}\implies 3Fe\:+\:Al_{2}(SO_{4})_{3}$

• Aluminium (Added to $ZnSO_{4}$ Solution.)

1. Zinc metal is settles down
2. {Inference} Al can displace Zn from $ZnSO_{4}$ solution.  $2Al + 3ZnSO_{4}\implies 3Zn\:+\:Al_{2}(SO_{4})_{3}$

• Aluminium (Added to $CuSO_{4}$ Solution.)

1. Copper metal is settles down
2. {Inference} Al can displace Cu from $CuSO_{4}$ solution.  $2Al + 3CuSO_{4}\implies 3Cu\:+\:Al_{2}(SO_{4})_{3}$

Metal Iron :

• Iron (Added to $CuSO_{4}$ Solution.)

1. Copper metal is settles down
2. {Inference} Fe can displace Cu from $CuSO_{4}$ solution.  $Fe + CuSO_{4}\implies Cu\:+\:FeSO_{4}$

• Iron (Added to $ZnSO_{4}$ Solution.)

1. Solution remains colourless.
2. {Inference} Fe can not displace Zn from $ZnSO_{4}$ solution.  

• Iron (Added to $Al_{2}(SO_{4})_{3}$ Solution.)

1. Solution remains colourless.
2. {Inference} Fe can not displace Al from $Al_{2}(SO_{4})_3$ solution.  

• Conclusion :

• Al > Zn > Fe > Cu.

• Precautions :

1. Do not touch any chemical.
2. Always clean the metallic strips before use with a sand paper.
