Which of the following statements is TRUE?
A) A reduction process corresponds to an increase in oxidation state as a result of loss of electrons.
B) An oxidation process involves the loss of electrons resulting in an increase in oxidation state.
C) An oxidation process corresponds to a decrease in oxidation state as a result of a gain of electrons.
D) During a reduction process electrons are lost, while during an oxidation they are gained.
E) During a reduction process an oxidation state increases, while in an oxidation process an oxidation state decreases.

Question

Quizplus · Accepted Answer

In an oxidation process, there is a loss of electrons, resulting in an increase in the oxidation state. This is because oxidation state is defined as the hypothetical charge that an atom would have if all of its bonds were 100% ionic. Therefore, if an atom loses electrons, its hypothetical charge would be more positive, resulting in an increase in oxidation state. Choice A is incorrect because it describes a reduction process, where there is a gain of electrons, resulting in a decrease in oxidation state. Choice C is also incorrect for the same reason. Choice D is incorrect because it describes the opposite of what actually happens during redox reactions. Finally, choice E is incorrect because it describes the opposite of what happens during an oxidation process.
