Silver crystals grow on a copper wire
name: Precipitation of silver from silver nitrate solution using copper wire
When copper wire is put in the silver nitrate solution, redox reaction between silver ions and copper metal occurs. Silver ions is reduced to silver metal. Copper is oxidizes to copper (II) ions. Thus the crystals of silver metals is obtained on the copper wires.
The rate of this reaction depands on concentration of silver ions. Because of this in the more consentrated solution more crystals grow.
