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 | No reaction | Displacement |
B | Displacement | No reaction | No reaction | No reaction |
C | No reaction | No reaction | No reaction | |
D | 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) Metal B is most reactive.
(ii) When metal B is added to copper (II) sulphate solution, displacement reaction occurs.
(iii) Metal B > Metal A > Metal C > Metal D
