Silver Tree

The video tutorial explains displacement reactions, where a more reactive metal displaces a less reactive one in a compound. It demonstrates this with an experiment using copper wire and silver nitrate solution. The copper wire, shaped like a tree, is submerged in the solution, leading to the growth of silver on the wire and a color change in the solution. The tutorial details the chemical process, where copper displaces silver ions, forming copper ions that turn the solution blue, while silver precipitates on the wire. The experiment confirms the displacement reaction through observable changes.

What is a displacement reaction?

• A reaction where a less reactive metal displaces a more reactive metal.

• A reaction where metals do not interact with each other.

• A reaction where two metals combine to form a new compound.

• A reaction where a more reactive metal displaces a less reactive metal from its compound.

What is the purpose of shaping the copper wire into a tree?

• To ensure the copper does not dissolve.

• To prevent the silver nitrate from reacting.

• To make the experiment visually appealing.

• To increase the surface area for the reaction.

What happens to the copper wire when it is submerged in silver nitrate solution?

• It remains unchanged.

• It dissolves completely.

• It gets coated with silver as the solution turns pale blue.

• It turns into a gas.

Why does the solution turn blue during the reaction?

• Due to the presence of copper ions in the solution.

• Because the silver nitrate is blue.

• Because of the formation of silver ions.

• Due to the reaction of nitrate ions.

What confirms the occurrence of the displacement reaction?

• The change in color of the solution and the tree.

• The formation of a gas.

• The copper wire dissolves completely.

• The solution remains colorless.
