QUESTION:

• What is displacement reactions?

ANSWER:

• Displacement reactions involve a metal and a compound of a different metal. In a displacement reaction:
• a more reactive metal will displace a less reactive metal from its compounds
• Displacement reactions are easily seen when a salt of the less reactive metal is in the solution. During the reaction:
• the more reactive metal gradually disappears as it forms a solution
• the less reactive metal coats the surface of the more reactive metal

EXAMPLE:

• For example, magnesium is more reactive than copper. When a piece of magnesium is dipped into blue copper sulfate solution:
• the blue colour fades as colourless magnesium sulfate solution forms
• brown copper coats the surface of the magnesium
