What concentration of sodium hypochlorite is typically recommended for bleach use?

• A. 2.5%
• B. 5.25%
• C. 10%
• D. 15%

Answer: (B)

The recommended concentration of sodium hypochlorite for bleach use is typically 5.25%. This concentration is effective for disinfecting surfaces and has been widely used for household cleaning and sanitization purposes. Sodium hypochlorite is the active ingredient in household bleach, and at this concentration, it offers a good balance of efficacy and safety for everyday use, making it suitable for a variety of surfaces in salons and households. Higher concentrations, like 10% or 15%, may pose greater risks due to their strength, which can lead to potential damage to surfaces or create an unpleasant environment due to fumes. Meanwhile, a lower concentration of 2.5% might not effectively eliminate germs and bacteria, making it less suitable as a disinfecting agent. Therefore, 5.25% is the commonly accepted standard for balance and effectiveness in disinfection practices.
