Final answer:
True, common household bleach containing sodium hypochlorite is an effective disinfectant, with a higher phenol coefficient than 1.0, indicating greater effectiveness compared to phenol.
Step-by-step explanation:
True, common household bleach is an effective disinfectant for the salon. Sodium hypochlorite, found in common household bleach, has been used since the 18th century as a disinfectant and bleaching agent. It decomposes to release chlorine, which acts as the active disinfecting agent. Chlorine-based products like sodium hypochlorite are compared to phenol in terms of efficacy, where they often have a phenol coefficient greater than 1.0, indicating higher effectiveness than phenol itself. Additionally, bleach is frequently used in various industries, including food processing and restaurants, to reduce the spread of foodborne diseases, demonstrating its broad-spectrum bactericidal properties.
