Here's the breakdown:
* Reactivity Series: Copper is more reactive than silver. This means copper has a stronger tendency to lose electrons and form positive ions.
* Displacement Reaction: When copper is placed in a silver nitrate solution (AgNO₃), the more reactive copper displaces the less reactive silver from its compound.
* Reaction: Copper atoms lose electrons and form copper(II) ions (Cu²⁺), while silver ions (Ag⁺) gain electrons and become solid silver atoms. This results in the formation of copper nitrate (Cu(NO₃)₂) and metallic silver.
Here's the chemical equation for the reaction:
Cu(s) + 2AgNO₃(aq) → Cu(NO₃)₂(aq) + 2Ag(s)
Observations:
* You'll see a blue solution form, which is the characteristic color of copper(II) nitrate.
* Silver crystals will deposit on the surface of the copper, appearing as a silvery coating.
Key Points:
* The reaction is driven by the difference in reactivity between copper and silver.
* The displacement reaction results in the formation of new compounds and a change in the physical appearance of the solution.
* This reaction is a classic example of a single displacement reaction.
