So all you need to do is enter the total alkalinity, CYA and pH Now wait-- the plot thickens --a new ion arrives. Unlike pH, which is a scale to measure on, total alkalinity is the amount of dissolved alkaline substances in water. Subscribe to Email Updates. In pool chemistry, many chemicals affect both pH and alkalinity: sanitizerssalt systemspH adjusters like acid and sodium bicarband specialty chemicals.

    M Alkalinity and P Alkalinity

    Thus the stage is set to define the alkalinity as follows: Alkalinity is the deviance from proton balance. On the pH scale, below neutral seven 7 is acidic. Note that equivalence points are not rigid quantities; they vary with the total content of carbonate DIC in the solution — as shown in this example. The pH of the water determines which form of ions are most prevalent. What's the difference between carbonate alkalinity and total alkalinity?
