Final answer:
Bleach is a disinfectant that is classified under the group of chemicals known as halogens, often containing chlorine compounds like sodium hypochlorite, utilized for their strong oxidizing properties against pathogens.
Step-by-step explanation:
Bleach is a disinfectant that falls under the group of chemicals known as halogens. Specifically, it often consists of a chlorine compound such as sodium hypochlorite. Halogens like chlorine, iodine, and fluorine are widely used for disinfection because they are effective at oxidizing cellular components and destabilizing vital macromolecules of pathogens. For example, chlorine in bleach works by breaking down the cell walls of microbes, leading to their death. Bleach is commonly used in household cleaning and disinfecting products and is particularly known for its use in water treatment processes.
The effectiveness of chemical disinfectants is often compared to phenol, but in the case of bleach, it is compared to other chlorine-based disinfectants.
