Which of the following characteristics is true for both oxidizing and reducing agents?

  1. Both receive electrons

  2. Both are used in disinfection processes

  3. Both give up electrons easily

  4. Neither can affect chemical reactions

The correct answer is: Both are used in disinfection processes

The statement that both oxidizing and reducing agents are used in disinfection processes is accurate because both types of agents play a crucial role in the mechanism of disinfection. Oxidizing agents, such as chlorine and ozone, are widely used to kill or deactivate microorganisms by oxidizing their cellular components, effectively rendering them inactive. Conversely, reducing agents can also contribute to disinfection in certain processes, such as those involving the reduction of chlorine residuals or other disinfectants in the presence of organic matter. Oxidizing agents gain electrons during chemical reactions while reducing agents donate electrons. This fundamental difference in how they interact with electrons explains why both agents can be involved in disinfection but serves specific roles depending on the context and desired outcome of the treatment process. Understanding the roles of both agents helps water operators effectively manage and optimize disinfection protocols in water treatment facilities.
