Question

In which pair
we see displacement reaction
a) Nacl solution and copper metal
b) Mgcl2 solution and aluminium metal
c) FeSo4 solution and silver metal
d) AgNO3 solution and copper metal​

Answer 1

Answer:

d. Copper metal being more reactive than Silver (Ag ).

Since it is more reactive a displacement reaction will occur

2AgNO3(aq) + Cu (s) → Cu (NO3) 2(aq) + 2Ag (s)
