Explain the concept of sacrificial protection with an example.
Sacrificial protection is a method of preventing corrosion by using a more reactive metal to protect a less reactive metal. The more reactive metal will corrode instead of the less reactive metal.
Sacrificial protection is a method of preventing corrosion by using a less reactive metal to protect a more reactive metal. The less reactive metal will corrode instead of the more reactive metal.
Sacrificial protection is a method of preventing rust by using a more reactive metal to protect a less reactive metal. The more reactive metal will not corrode.
Sacrificial protection is a method of accelerating corrosion by using a more reactive metal to protect a less reactive metal. The more reactive metal will not corrode.
Answer explanation
Sacrificial protection prevents corrosion by using a more reactive metal to protect a less reactive metal. The more reactive metal corrodes instead of the less reactive metal.

Discuss the disadvantages of sacrificial protection in chemistry.
Requires advanced technical knowledge to implement
Constant supply of sacrificial material and effectiveness only in direct contact with the metal being protected
Can only be used in high temperature environments
Results in toxic byproducts
Answer explanation
Sacrificial protection has disadvantages such as requiring advanced technical knowledge, needing a constant supply of sacrificial material, and being effective only in direct contact with the metal being protected.
