Boiler feed water is considered neutral in pH at what value?

8.3
7.0
10 to 11
6.5

The correct answer is: 7.0

Boiler feed water is considered neutral in pH at a value of 7.0 because this is the standard pH level where water is neither acidic nor basic. The pH scale ranges from 0 to 14, with values below 7 indicating acidity and values above 7 indicating alkalinity. A pH of 7 means that the concentration of hydrogen ions is equal to that of hydroxide ions, which signifies a balanced state. Maintaining a neutral pH in boiler feed water is crucial for preventing corrosion and scaling within the boiler system. Deviations from this neutral pH can lead to various complications, such as damage to equipment and reduced boiler efficiency. Water with a pH lower than 7 can be corrosive, while water with a higher pH may lead to the formation of deposits that can adversely affect the performance of the boiler.
