Question

What do you infer from the following and also mention the type of reaction involved:
1.CuSO4+Fe-FeSO4+Cu
2.FeSO4+Zn-ZnSO4+Fe
3.2AgNO3+Cu-Cu(NO3)2+2Ag

Answer 1

all are example for displacement reaction

Answer 2

we infer that the more reactive element displaces a less reactive element from their salt solution.
1:- iron displaces copper
2:-zinc displaces iron
3;- copper displaces silver

the type of reaction involved is displacement reaction
