Chemistry Quiz: Sacrificial Protection

What is the definition of sacrificial protection in chemistry?

• A method of protection using a non-reactive metal

• A method of protection using a gas

• A method of protection using a polymer

• A method of corrosion protection using a more reactive metal

Answer explanation

Sacrificial protection is a method of corrosion protection using a more reactive metal.

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.

What are the advantages of using sacrificial protection in chemistry?

• It causes rapid corrosion of metals

• It provides effective corrosion protection for metals.

• It is expensive and not cost-effective

• It has no impact on preventing corrosion

Answer explanation

Sacrificial protection provides effective corrosion protection for metals.

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.

How is sacrificial protection applied in real life situations?

• By exposing the metal to extreme temperatures

• By painting the metal surface with a protective coating

• By applying a strong acid to the metal surface

• By using a more reactive metal to protect a less reactive metal from corrosion

Answer explanation

Sacrificial protection is applied by using a more reactive metal to protect a less reactive metal from corrosion.

Compare sacrificial protection with other methods of protection in chemistry.

• Sacrificial protection involves using a more reactive metal to speed up the corrosion of a less reactive metal.

• Sacrificial protection involves using a more reactive metal to protect a less reactive metal from corrosion.

• Sacrificial protection is the same as using a protective coating on metal surfaces.

• Sacrificial protection is a method of protecting metals by exposing them to extreme temperatures.

Answer explanation

Sacrificial protection uses a more reactive metal to protect a less reactive metal from corrosion.

Define sacrificial protection and its significance in chemistry.

• A method of creating chemical reactions using non-reactive metals

• A process of protecting metals by painting them with a special coating

• A technique of using heat to prevent corrosion in metals

• A method of corrosion prevention using a more reactive metal to protect a less reactive metal.

Answer explanation

Sacrificial protection is a method of corrosion prevention using a more reactive metal to protect a less reactive metal.

Provide an example of sacrificial protection used in the field of corrosion prevention.

• Using zinc coating to protect steel from corrosion

• Using aluminum coating to protect wood from corrosion

• Spraying water on iron to prevent oxidation

• Applying a layer of plastic to prevent rust on metal

Answer explanation

Sacrificial protection is exemplified by using zinc coating to safeguard steel from corrosion.

What are the benefits of sacrificial protection in chemical processes?

• Causing damage to equipment

• Preventing corrosion

• Increasing corrosion

• Reducing chemical reactions

Answer explanation

Sacrificial protection prevents corrosion in chemical processes.

Explain the drawbacks of sacrificial protection in chemical applications.

• Sacrificial protection is free and provides complete protection in all areas of the metal surface.

• Sacrificial protection can be easily implemented and does not require any maintenance.

• Sacrificial protection is not effective in preventing corrosion in chemical applications.

• Sacrificial protection can be costly and may not provide complete protection in all areas of the metal surface.

Answer explanation

Sacrificial protection can be costly and may not provide complete protection in all areas of the metal surface.
