The position of some metals in the electrochemical series in decreasing electropositive character is given as M g > A l > Z n > C u > A g . What change will happens, if a copper spoon is used to stir a solution of aluminium nitrate?

Options

  1. AThe solution becomes blue
  2. BThe spoon will get coated with A l
  3. CAn alloy of C u and A l is formed
  4. DThere is no reaction

Correct answer

D. There is no reaction

Step-by-step solution

The metal placed below (less reactive) in electrochemical series does not react with that metal salt solution which metal is placed above (more reactive) in series.
