Question

which metal can displace Ag metal from dicyanoargantate solution??​

Answer 1

Answer:

This answer can be explained by Reduction potential values:

Zn+2+2e−⟶Zn  [−0.76]

Ag++e−⟶Ag         [0.22]

Cu++e−⟶Cu        [0.52]

Fe+3+e−⟶Fe+2   [0.77]

As the reduction potential for Zn is low it can replace that element from their compound state for which their reduction potential is above than that.
