Q1.
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.
Samples of four metals $A$,$B$,$C$ and $D$ were taken and added to the following solutions 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 | Displacement | No reaction | Displacement |
| $C$ | No reaction | No reaction | No reaction | Displacement |
| $D$ | No reaction | No reaction | No reaction | No reaction |
