The position of some metals in the electrochemical series in the decre

1.	The position of some metals in the electrochemical series in the decreasing order of electropositive character is given : Mg > Al > Zn > Cu > Ag1. What would happen if a copper spoon is used to stir a solution of aluminium?2. Is there any reaction?3. Comment on your response and justify.
Answer» 1. Nothing will happen. The Al solution can be safely stirred using a Cu spoon. 2. No. 3. The Cu spoon will not react with the solution of Al. Greater the value of reduction potential of a metal, more easily it is reduced. The element having low reduction potential is more reactive and is oxidised. Cu has greater reduction potential than Al and is more active metal than Cu.

1. Nothing will happen. The Al solution can be safely stirred using a Cu spoon.

2. No.

3. The Cu spoon will not react with the solution of Al. Greater the value of reduction potential of a metal, more easily it is reduced. The element having low reduction potential is more reactive and is oxidised. Cu has greater reduction potential than Al and is more active metal than Cu.
