Reactivity and Displacement Reactions

The video explains a single displacement reaction where a more reactive metal displaces a less reactive metal from its compound. In the experiment, copper wire is added to a silver nitrate solution. Copper, being more reactive, replaces silver ions, forming silver metal on the wire. After 30 minutes, a significant amount of solid silver forms, and the solution turns blue due to copper ions.

What happens in a single displacement reaction involving metals?

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

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

• Two metals combine to form a new compound.

• A metal reacts with a non-metal to form a salt.

Which metal is more reactive in the experiment described?

• Silver

• Copper

• Both are equally reactive

• Neither is reactive

What is added to the silver nitrate solution in the experiment?

• Iron wire

• Zinc wire

• Silver wire

• Copper wire

What forms on the copper wire as the reaction occurs?

• Copper metal

• Silver metal

• Gold metal

• Iron metal

Why does the solution turn blue during the reaction?

• Due to the formation of iron ions

• Due to the formation of zinc ions

• Due to the formation of copper ions

• Due to the formation of silver ions
