The HOCl-NaOCl buffer system is effective in the pH range of 6.5-8.5. This is because at a pH of 7.4 (physiological pH), HOCl and OCl- ions are present in roughly equal amounts, making the buffer system highly effective. Outside this range, the buffer system will not be as effective in resisting changes in pH. Therefore, option C is the correct answer.
