In electroplating, the article to be electroplated serves as
1 Cathode

The position of some metals in the electrochemical series in decreasing electropositive character is given as \(Mg > Al > Zn > Cu > Ag.\) What will happen, if a copper spoon is used to stir a solution of aluminium nitrate
1 The spoon will get coated with \(Al\)
2 An alloy of \(Cu\) and \(Al\) is formed
3 The solution becomes blue
4 There is no reaction
Explanation:
(d)The metal placed below in electrochemical series does not react with that metal salt solution which metal is placed above in series.
