Reactivity Series of Metals

What does displacement mean?

• A chemical reaction where a less reactive metal takes the place of a more reactive metal in a compound.

• A chemical reaction where a more reactive metal takes the place of a less reactive metal in a compound.

• A more reactive metal is removed from a compound.

Which one of the following equations correctly represents the reaction of silver nitrate with copper metal?

• CuNO₃(aq) + Ag(s) → Cu(s) + AgNO₃(aq)
• Cu(s) + 2 AgNO₃(aq) → Cu(NO₃)₂(aq) + 2 Ag(s)
• Cu(s) + AgNO₃(aq) → CuNO₃(aq) + Ag(s)
• Cu(s) + Ag(NO₃)₂(aq) → Cu(NO₃)₂(aq) + Ag(s)

When scrap iron is added to blue copper sulphate solution, a pinky-brown deposit is formed and a pale green solution is left above it. The pale green solution is of?

•  iron oxide
• copper chloride
• sulphuric acid
• iron sulphate

If the metal is more reactive than the metal in the compound it completes with the less reactive metal. Therefore, it can concluded that ...

• The less reactive metal repel the more reactive metal from its compound
• The more reactive metal bonded with  the less reactive metal from its compound
• The less reactive metal pushes out or displaces the more reactive metal from its compound
• The more reactive metal pushes out or displaces the less reactive metal from its compound

What will be reaction if less reactive metal is added in a solution with more reactive metal compound?

• vigorous reaction
• fizzing gas produced
• burns moderately
• no reaction
