Question
Define reduction in the context of redox reactions, specifying what happens to the species that is reduced.
Answer
Reduction is the gain of electrons by a species, which results in a decrease in its oxidation state.
Explanation
The answer correctly states that reduction involves electron gain and links it to a lower oxidation state, directly addressing the learning objective. It demonstrates understanding of the electron-transfer definition required at the HT level.
Common mistake
Misunderstanding Reduction
Students often confuse reduction with the addition of oxygen instead of the gain of electrons.
Remember that reduction specifically refers to the gain of electrons, while oxidation is the loss of electrons.
