Acidic contamination or localized low-pH excursions are normally required to generate atomic hydrogen. In high-purity systems, raw water in-leakage (e.g., condenser leakage) lowers boiler water pH when magnesium hydroxide precipitates, resulting in corrosion, formation of atomic hydrogen, and initiation of hydrogen attack.
The quality of feedwater required is dependent on boiler operating pressure, design, heat transfer rates, and steam use. Most boiler systems have sodium zeolite softened or demineralized makeup water. Feedwater hardness usually ranges from 0.01 to 2.0 ppm, but even water of this purity does not provide deposit-free operation.
It was an easy lesson. The juice was acidic and the baking soda was alkaline so the juice showed a low pH by turning the litmus paper a certain color; and the Arm & Hammer showed a higher pH by doing a similar thing. The pH scale went from zero to 14 and the number seven was neutral. When we measure pH, we're measuring the power of Hydrogen.

and critical for normal boiler service life and correct operation. This is water free of excessive minerals and gases with a nominal pH of 7.8 ± 0.5. A pH reading of around 10.0 or higher can result in priming and surging, which can cause wet steam and/or flooding of the steam supply and steam header. A pH level only a single digit away from
For example, a pH of 4 is ten times more acidic than a pH of 5 and 100 times (10 times 10) more acidic than a pH of 6. The same holds true for pH values above 7, each of which is ten times more alkaline (another way to say basic) than the next lower whole value. For example, a pH of 10 is ten times more alkaline than a pH of 9.
Boiler water pH refers to a quantitative figure that expresses the acidity or alkalinity of boiler water. Ideally it should be between 8.5 and 9.5. If the pH is lower than that, the boiler water will start eating the pipes and attacks the boiler equipments as well.
