Which of the following is an indicator of proper pH levels in feed water?

The indicator of proper pH levels in feed water is a neutral pH of 7. Water with a neutral pH signifies that it is neither acidic nor alkaline, which is essential in various applications, especially in processes that require balanced conditions, such as in water treatment and boiler operations. A pH of 7 promotes optimal conditions for chemical reactions and helps prevent corrosion and scaling within systems. Maintaining this neutral pH level ensures the effectiveness of certain processes and protects equipment from damage that can be caused by extreme acidity or alkalinity. Understanding the importance of pH in feed water is crucial for effectively managing water quality and system performance.
