Question
In oxidation-reduction reactions, one substance loses electrons (oxidation) while another substance gains electrons (reduction). A convenient way to recognize oxidation is to look for an increase in charge. Similarly, a convenient way to recognize reduction is to look for a decrease in charge. Consider the following equation: 2MgO(s)→2Mg(s) + O₂(g) Here is the same reaction, but with the ionic compound MgO rewritten to show its individual ions: 2Mg2+ + 202- →2Mg(s) + O2(g) Now it is much clearer to see that magnesium decreases in charge (reduction) while oxygen increases in charge (oxidation).
