# SECTION 1: CORROSION FUNDAMENTALS
### Question 1.1
**What is the primary electrochemical reaction that occurs at the anode in the corrosion of
iron?**
A) O₂ + 2H₂O + 4e⁻ → 4OH⁻
B) Fe → Fe²⁺ + 2e⁻
C) Fe²⁺ + 2e⁻ → Fe
D) 2H⁺ + 2e⁻ → H₂
**Correct Answer: B**
**Rationale:** The anodic reaction in iron corrosion is the oxidation of iron metal to ferrous
ions, represented as Fe → Fe²⁺ + 2e⁻. This is the oxidation (loss of electrons) reaction that occurs
at the anode. Option A represents the cathodic oxygen reduction reaction, Option C is the reverse
(reduction of iron), and Option D is the hydrogen evolution reaction.

### Question 1.2
**Which of the following is NOT a necessary component of a corrosion cell?**
A) Anode
B) Cathode
C) Electrolyte
D) External power source
,Page 3 of 179
**Correct Answer: D**
**Rationale:** A corrosion cell requires four essential components: an anode (where
oxidation occurs), a cathode (where reduction occurs), an electrolyte (conductive medium), and a
metallic connection (electrical path) between the anode and cathode. An external power source is
not required for a galvanic corrosion cell; it is required for impressed current cathodic protection
systems, not for basic corrosion cells.
---
### Question 1.3
**Crevice corrosion typically occurs in which of the following locations?**
A) On exposed flat surfaces
B) In confined spaces where stagnant solution is trapped
C) At high temperatures only
D) Under cathodic protection
**Correct Answer: B**
**Rationale:** Crevice corrosion occurs in shielded areas where stagnant solution is
trapped, such as under gaskets, washers, bolt heads, or surface deposits. The stagnant conditions
lead to differential aeration and localized acidification, creating an aggressive environment that
accelerates corrosion in these confined spaces.
---
### Question 1.4
, Page 4 of 179
**What is passivation in the context of corrosion?**
A) The acceleration of the anodic reaction rate
B) The complete prevention of all corrosion reactions
C) A reduction of the anodic reaction rate of an electrode involved in corrosion
D) The formation of a galvanic couple between two dissimilar metals
**Correct Answer: C**
**Rationale:** Passivation is a reduction of the anodic reaction rate of an electrode involved
in corrosion. This occurs when a metal surface forms a thin, protective oxide layer that slows
down the corrosion process. Stainless steel, for example, relies on a passive chromium oxide film
for its corrosion resistance.
---
### Question 1.5
**According to the galvanic series, which of the following metals is most anodic (active) and
will corrode preferentially?**
A) Gold
B) Stainless steel (passive)
C) Zinc
D) Copper
**Correct Answer: C**
