| (i) \[\text{Mg+CuS}{{\text{O}}_{\text{4}}}\to \text{MgS}{{\text{O}}_{\text{4}}}\text{+Cu}\] |
| (ii) \[\text{Ca+MgS}{{\text{O}}_{\text{4}}}\to \text{CaS}{{\text{O}}_{\text{4}}}\text{+Mg}\] |
| (iii) \[\text{Cu+ZnS}{{\text{O}}_{\text{4}}}\to \text{CuS}{{\text{O}}_{\text{4}}}\text{+Zn}\] |
| (iv) \[\text{Fe+MgS}{{\text{O}}_{\text{4}}}\to \text{FeS}{{\text{O}}_{\text{4}}}\text{+Mg}\] |
A) (iii) and (iv) only
B) (i) and (iv) only
C) (ii) and (iii) only
D) (i) and (ii) only
Correct Answer: D
Solution :
As per reactivity series, the reactivity order is\[\text{CaMgZnFeCu}\]. Hence, only reactions (i) and (ii) are possible as more reactive metal can displace a less reactive metal from its salt.
