Proper pH measurement is critical to control
corrosion and deposition in water systems. The parameter pH
is defined as the opposite of the logarithm (base 10) of the
concentration of hydrogen ions in grams / liter
(g/l).
In pure water, hydrogen ions (H+) exist
in equilibrium with hydroxyl ions (OH - ). At
25°C, the concentration of hydrogen ions is equal to 10
- 7 g/l. Thus, pure water has a pH of 7. As the
concentration of hydrogen ions increases, the water becomes
more acidic, and the pH decreases.
Basics of pH measurement. There are a few
basics guidelines for pH measurement in water
systems:
