ABYC CORROSION EXAM 2025 NEWEST WITH ACTUAL QUESTIONS AND CORRECT
VERIFIED ANSWERS (100% GUARANTEED PASS!!!)
GFCI stands for... - (ANSWER)Ground Fault Circuit Interrupter
T/F A galvanic isolator WILL block stray AC. - (ANSWER)False. A galvanic isolator WILL NOT block AC. It
will only blocks stray DC that is moving through the green grounding conductor.
T/F An isolation transformer makes a galvanic isolator unnecessary. - (ANSWER)True.
An isolation transformer works through electromagnetic _________. - (ANSWER)Induction
A reverse polarity indicator is placed between which two wires? Why? - (ANSWER)White neutral and
green grounding.
If the black hot and white neutral are reversed, electricity will flow through the white neutral
illuminating the indicator light and leaving through the green grounding conductor.
Bonding wires shall be at least #__ AWG - (ANSWER)#8 AWG
Electrolytic corrosion is commonly known as: - (ANSWER)Stray-current corrosion
Stray-current corrosion is technically called: - (ANSWER)Electrolytic corrosion
Matter can exist as a - (ANSWER)Solid, liquid, or gas
Matter is made from - (ANSWER)Molecules
Molecules are made of - (ANSWER)Atoms
,ABYC CORROSION EXAM 2025 NEWEST WITH ACTUAL QUESTIONS AND CORRECT
VERIFIED ANSWERS (100% GUARANTEED PASS!!!)
Atoms are made of - (ANSWER)protons, neutrons, electrons
The atom is electrically - (ANSWER)Neutral. That's because the particles that comprise an atom balance
each other.
the outer shell of an atom is called the - (ANSWER)Valence shell
When the valence shell of an atom is completely filled, the atom is in its most ______ state. -
(ANSWER)Stable.
Atoms that have gained or lost an electron are known as - (ANSWER)Ions
T/F Ions can have positive or negative charges? - (ANSWER)True.
Define Ionization - (ANSWER)The process by which an atom or molecule acquires a charge.
What are the two types of chemical bonds? - (ANSWER)Covalent and ionic
In covalent bonds, atoms form chemical bonds by _______ electrons. - (ANSWER)Sharing.
E.g. water, H2O
In ionic bonds, atoms form chemical bonds by _______ electrons. - (ANSWER)Giving up or gaining
electrons.
, ABYC CORROSION EXAM 2025 NEWEST WITH ACTUAL QUESTIONS AND CORRECT
VERIFIED ANSWERS (100% GUARANTEED PASS!!!)
The atom giving an electron become a positive ion. The atom gaining an electron becomes a negative
ion. Oppositely charged bodies are attracted to each other, bonding them together.
E.g. Sodium Chloride, NaCl, table salt.
T/F Atoms in the valence shell are involved in the corrosion process? - (ANSWER)True
What is disassociation with regard to electrolyte? - (ANSWER)When an ionic substance (like sodium
chloride, table salt) is immersed in water it disassociates, or separates, into positive and negative ions.
__________ are electrical conductors in which current is carried by ions rather than by free electrons. -
(ANSWER)Electrolytes
The three categories of corrosion are: - (ANSWER)Electrochemical, galvanic, and electrolytic
Single-metal corrosion is technically referred to as - (ANSWER)Electrochemical corrosion
Electrochemical corrosion is commonly known as - (ANSWER)Single-metal corrosion
Galvanic corrosion is sometimes referred to as - (ANSWER)Two-metal corrosion or bi-metallic corrosion
Corrosion is often improperly called - (ANSWER)Electrolysis.
Electrolysis is what happens to the electrolyte not the metals involved.
