What percentage of available chlorine does sodium hypochlorite in its commercial form contain?

• A. 5-7%
• B. 8-10%
• C. 10-12%
• D. 12-15%

Answer: (C)

Sodium hypochlorite in its commercial form typically contains between 10-12% available chlorine. This concentration is widely used in pool sanitation and disinfection because it effectively kills bacteria and other pathogens, making water safe for swimming. The percentage indicates the strength of the solution; therefore, knowing the concentration helps pool operators determine the appropriate dosage for chlorination purposes. Higher concentrations of sodium hypochlorite can lead to increased disinfection effectiveness but may also require careful handling due to potential hazards associated with strong chlorine solutions. This makes the 10-12% range practical for use as it balances effectiveness with safety and manageability in pool maintenance.
