Which of the following is an example of a chemical used for sanitizing?

Chlorine is a well-known chemical sanitizer that kills bacteria and viruses, making it a common choice in food service establishments for sanitizing surfaces and utensils. It works effectively to reduce the number of pathogens present, ensuring that the environment is safe for food preparation and handling. Chlorine-based sanitizers are favored due to their ability to quickly kill a wide range of microorganisms when used properly and at the right concentration.

The other options, while they have their specific uses in cleaning and maintenance, do not serve primarily as sanitizers. Detergents are used to remove dirt and grease but do not have the same sanitizing properties as chlorine. Acidic cleaners, while effective for removing mineral deposits and specific types of stains, do not provide the broad-spectrum microbial kill that sanitizers do. Abrasive cleaners are used for scrubbing surfaces clean, but they do not possess sanitizing capabilities. Thus, chlorine stands out as the primary example of a chemical that effectively sanitizes, ensuring food safety in various environments.
