Question

Write the chemical reaction when Cu rod is placed in solution of silver nitrate.

Answer 1

Metallic copper and silver nitrate solution following redox reaction as indicated below:

Cu ( S)+2 AgNO3( Aq) = 2Ag(S) + Cu(NO3)2 ( Aq).

Solid copper reacts with silver nitrate solution to produce sold silver and copper nitrate salt, Copper oxidized by releasing two electrons which is transferred to two silver ions to precipitate metallic silver which is called reduction.

Nitrate ion has no role and act as a spectator kind of ion.

Answer 2

metallic Copper and Silver Nitrate
