Which substance loses electrons in a chemical reaction.

The reducing agent is a substance that causes reduction by losing electrons; therefore its oxidation state increases. The simplest way to think of this is that the oxidizing agent is the substance that is reduced, while the reducing agent is the substance that is oxidized as shown in Figure 8.2. 1 and summarized in Table 8.2. 1.4.
