Question: Which application of electrochemistry is used for corrosion prevention?

Options:

Correct Answer: Cathodic protection

Solution:

Cathodic protection prevents corrosion by making the metal surface the cathode in an electrochemical cell.

Which application of electrochemistry is used for corrosion prevention?

Which application of electrochemistry is used for corrosion prevention?

Step 1: Understand that corrosion is the process where metals deteriorate due to chemical reactions, often with oxygen and moisture.
Step 2: Learn that electrochemistry studies the relationship between electricity and chemical reactions.
Step 3: Identify that cathodic protection is a method used to prevent corrosion.
Step 4: Know that in cathodic protection, the metal that needs protection is made the cathode in an electrochemical cell.
Step 5: Realize that by making the metal the cathode, it prevents the metal from losing electrons and corroding.
