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

Question

Quizplus · Accepted Answer

When dealing with ionic materials, it is common for the oxidation state of an ion to change as a result of gaining or losing electrons. Therefore, the most useful definition of oxidation is the loss of electrons, which would indicate that an ion is becoming more positively charged (i.e. it is losing negatively charged electrons). A and C are less useful because not all ionic materials involve oxygen or hydrogen, respectively. D is incorrect because, as stated above, the definition of oxidation involving loss of electrons is the most useful in this context.
