NACE (National Association of Corrosion
Engineers) CP1 Tester Exam Questions &
Answers
1.Corrosion
A) is defined by NACE International as the deterioration of a material,
usually a metal that results from a reaction with its environment.
B) is produced when acids dissociate, when cation takes place
C) is the division of chemistry that deals with the transfer of electric
charge in chemical reactions
D) involves the movement of electrons anode to cathode for the
reduction reaction to occur
E) is equal to the reciprocal of resistivity.
Answer: a
2.Atoms
A) are positively charged particles in the nucleus
B) are neutral particles in the nucleus
C) are electrically charged atoms

E) is an ionized solution capable of conducting electricity.
Answer: b
8.Molecules
A) is produced when acids dissociate, when cation takes place
B) is the term applied to the loss of one or more electrons from an atom
or molecule, which forms a positively charged ion, the atom or
molecule decreases in negative charge (occurs at the anode)
C) are composed of two or more atoms, molecules are the smallest unit of a
substance with the same specific chemical properties of that substance
