1.	The position of some metals in the electrochemical series in decreasing electropositive character is given as `Mg gt Al gt Zn gt Cu gt Ag`. What will happen, if a copper spoon is used to stir a solution of aluminium nitrateA. The spoon will get coated with AlB. An alloy of Cu and Al is formedC. The solution becomes blueD. There is no reaction
Answer» Correct Answer - D The metal placed below in electrochemical series does not react with that metal salt solution which metal is placed above in series.
