Q
Q: Which of the following is a common application of electrochemistry in corrosion prevention?
Solution: Cathodic protection is a technique that prevents corrosion by making the metal surface the cathode of an electrochemical cell.
Steps: 5
Step 1: Understand what corrosion is. Corrosion is the process where metals deteriorate due to chemical reactions, often with water or air.
Step 2: Learn about electrochemistry. Electrochemistry is the study of chemical processes that involve electricity.
Step 3: Know what cathodic protection is. Cathodic protection is a method used to prevent corrosion by using electrical currents.
Step 4: Identify the role of the cathode. In cathodic protection, the metal that needs protection is made the cathode, which helps prevent it from corroding.
Step 5: Recognize that this technique is widely used in various applications, such as pipelines and ships, to protect them from corrosion.
