What happens when the copper is placed into the solution?
The copper and the silver solution will react to form a silver precipitate. This precipitate will look textured and white at first and then turn to silver slivers.
What is the shiny, thread-like precipitate (solid) that is formed on the copper?
This precipitate is silver from the silver nitrate.
Why it happened: The silver metal formed on the copper because the only place the silver ions could gain electrons was on the surface of the copper where the atoms give up electrons.
The ideas behind this activity are the formation of a solid from a solution and the change in color of the solution due to the oxidation of copper.
Ions are elements that have either a positive or negative charge resulting from the loss or gain of electrons. The reaction in this activity results from silver ion and nitrate ion in the solution.
The copper that is added to the solution is an element. The reaction that takes place between the silver and the copper is called a redox reaction. This stands for reduction and oxidation, which refer to the gain and loss of electrons, respectively.
The silver will be reduced, gain one electron, and the element copper (Cu) will be oxidized, losing two electrons, to form the Cu ion. The white solid that begins to form on the surface of the copper is silver metal, the product of the reduction.

- DID YOU KNOW…. Why did the liquid (Silver Nitrate) turn bluish green?
What is the Statue of Liberty made of? The Statue of Liberty is made of copper 3/32in.thick, the same as two pennies put together.
Why is the Statue green?
The Statue of Liberty is green because of oxidation from the air which is accelerated by pollution and acids. This thin layer on the copper is called patina. The Statue of Liberty took 25 years to achieve its green color, but today that time would be much less because of air pollution
The Statue's copper has naturally oxidized to form its familiar "patina" green coating.
