Q
(5) considerations of ph
A
- Ph of solutions is a measurement of how acidic or basic a solution is
- Ph has an effect on chlorine disinfection and formations of thms
- Most important parameter in water
- Solutions containing more hydrogen ions than hydroxide ions are acidic and below pH 7.0
- Solutions with more hydroxide ions than hydrogen ions are basic and pH below 7.0
