Answer :
Black layer was deposited due to 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)
The above reaction is a displacement reaction in which an atom or a group atom displaces another atom from its compound.
