Lesson 1 Chapter 1

Question 1

atrnode: The cathode is the area of the metal surface that reduces (loses oxygen)

Answer 1

does not corrode and IS

Question 2

prOtected. The metal forms negatively charged anions that migrate to the anode through the electrolyte.

Question 3

Electrons flow from the anode toward the cathode in the metallic pathway.

Question 4

Reduction: A chemical reaction that occurs at the cathode that involves the gain of electrons to the

Question 5

metal. Reduction and oxidation alvways occur together through an exchange of electrons at specific

Question 6

sites on the metal surface.

Question 7

3. Metallic pathway: The metallic pathway connects the anode and cathode and allows the passage of

Question 8

electrons generated at the anode to the cathode. The metallic pathway is often the underlying metal

Question 9

substrate.

Question 10

4. Electrolyte: The electrolyte is a conductive medium in which ions are carried from the anode to the

Question 11

cathode. The electrolyte is any solution capable of conducting electricity

Answer 11

such as water.

Question 12

All four of the components of the electrochemical cell (anode

Answer 12

cathode

Question 13

present for corrosion to occur. Removing one or more of them prevents corrosion from occurring. As you can

Question 14

imagine

Answer 14

it is not always possible or practical to remove these components

Question 15

called corrosion control.

Question 16

An easy way to remember the components of the electrochemical cell is by the acronym of ACME: Anode
