Proper pH control of what range provides better chlorine efficiency?

6.8-7.0
7.0-7.2
7.2-7.4
7.4-7.6

The correct answer is: 6.8-7.0

Chlorine efficiency is improved when the pH is within a specific range. A pH of 6.8-7.0 is the most ideal range for proper chlorine efficiency. Option B, 7.0-7.2, is too high and can decrease the effectiveness of the chlorine. Options C (7.2-7.4) and D (7.4-7.6) are even higher and may lead to further inefficiency. It is important to note that maintaining a consistent pH level within the recommended range is crucial in order for the chlorine to effectively disinfect water. Therefore, the best option for proper chlorine efficiency is within the range of 6.8-7.0.
