Multiple Choice
In the context of redox reactions, which term best describes a reduction process?
A
Loss of electrons by a species
B
Increase in oxidation number of a species
C
Gain of electrons by a species
D
Gain of oxygen atoms by a species
Verified step by step guidance1
Understand that redox reactions involve two simultaneous processes: oxidation and reduction.
Recall that oxidation is defined as the loss of electrons by a species, which results in an increase in its oxidation number.
Recognize that reduction is the opposite process, meaning it involves the gain of electrons by a species.
Note that gaining oxygen atoms is often associated with oxidation, not reduction, because oxygen is highly electronegative and tends to increase oxidation states.
Therefore, the term that best describes a reduction process is 'Gain of electrons by a species' because reduction always involves electron gain.
