Solution- silver nitrate ,copper sulphate, zinc chloride and sodium chloride.
Some metals and some metallic and metallic salt are given.
a) Among them which metal can displace the metals from silver nitrate alone
b)In which solution no displacement is possible with the given metals .why?

Answer 1

1.

Mg

2.

Displacement reaction does not occur because copper metal is less reactive than iron metal.So a less reactive metal copper cannot displace a more reactive metal iron from its salt solution,iron sulphate solution.

its the answer.....
