Samples of four metals A, B, C and D were taken and added to the following solution one by one. The results obtained have been tabulated as follows.
|Metal||Iron (II) sulphate||Cooper (II) sulphate||Zinc sulphate||Silver nitrate|
|C.||No reaction||No reaction||No reaction||Displacement|
|D.||No reaction||No reaction||No reaction||No reaction|
Use the Table above to answer the following questions about metals A, B, C and D.
(i) Which is the most reactive metal?
(ii) What would you observe if B is added to a solution of copper (II) sulphate?
(iii) Arrange the metals A, B, C and D in the order of decreasing reactivity.
(i) B is most reactive metal.
(ii) B will displace copper from copper sulphate.
(iii) Arrangement of metals in the order of decreasing reactivity B>A>C>D.
