WebThe pH scale runs from 0-14, with 0 indicating a very strong acid, and 14 representing highly basic conditions. A solution with a pH of 7 is considered neutral, as is the case for pure … WebWhen the pH gets to 8.3 and above, bicarbonate ions convert into carbonate ions (CO 3 2-), and they bind really well with calcium (Ca 2+). So when your pH gets too high (over 8.3), calcium can precipitate out of solution even if the overall LSI of your pool is balanced. You can see this phenomenon for yourself.
WebGenerally, ion chromatography is used to analyze element ions and low-molecular ions that exist in a charged state in water. Ions can be classified as inorganic ions, organic acid ions, amines, etc. Care must be taken with the environment when performing ion chromatography analysis.
