What will happen if both copper and silver are placed in contact with solutions containing both Cu2+ and Ag+ ions

Sagot :

When solid copper is placed in Ag+ solution, the solution becomes faintly blue as copper metal is oxidized to Cu2+. White slivers of silver metal appear on the surface of the copper as Ag+ is reduced to silver metal.

Cu(s) + Ag+(aq) —> Cu2+(aq) + Ag(s)
