Which of the following definitions of reduction is generally most useful when dealing with ionic materials?

Question

Quizplus · Accepted Answer

When dealing with ionic materials, reduction typically involves the gain of electrons. This is especially relevant with respect to metal ions in solution, where the transfer of electrons between the metal ion species and the surrounding solvent ultimately leads to reduction of the metal ion to a lower oxidation state. In contrast, gain of hydrogen and loss of oxygen are more commonly associated with organic reactions, and are less likely to be directly relevant to ionic compounds.
