When copper is dipped in silver nitrate , copper being more reactive than silver, displaces silver from it's solution to form copper nitrate.
The black layer is silver.
The solution is copper nitrate.
Cu + AgNO3 -------> Cu(NO3)2 + Ag.
Hope it helped.....

Black layer was deposited due to the coating of silver because copper being more reactive than silver, displaced silver from silver nitrate solution.
2AgNO3(aq)+Cu → Cu(NO3)2(aq)+2Ag(S)
