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 Copper(II) Sulphate Zinc sulphate Silver nitrate A No reaction Displacement B Displacement No reaction 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 question about metals: A , B , C , and D . Which is the most reactive metal?

From the given table we can write the following observations: 1) A is less reactive than F e but more reactive than C u . 2) B is more reactive than F e but less reactive than Z n . 3) C is more reactive than A g but less reactive than F e , C u a n d Z n . 4) D is less reactive than F e , C u , Z n , A g . Hence, B is more reactive as per the drawn conclusions from statements 1, 2, 3, 4.

Metal Iron(II) sulphate Copper(II) Sulphate Zinc sulphate Silver nitrate A No reaction Displacement B Displacement No reaction 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 question about metals: A , B , C , and D . What would you observe if B is added to a solution of Copper I I sulphate?

The blue colour of copper sulphate solution disappears, and a reddish-brown copper metal is deposited on the metal B . This is because B is more reactive than Cu and it displaces copper from its solution.

Arrange the metals A , B , C , and D in the order of decreasing reactivity

From the given table we can write the following observations: 1) A is less reactive than F e but more reactive than C u . 2) B is more reactive than F e but less reactive than Z n . 3) C is more reactive than A g but less reactive than F e , C u a n d Z n . 4) D is less reactive than F e , C u , Z n , A g . B > A > C > D is the order of reactivity.
