Bicarbonate and carbonate are in a balance between the pH range of 8.2 to 8.4 at the low end and 9.6 at the high end. At a pH of 9.6, there is no carbon dioxide or bicarbonate, and all alkalinity is carbonate. As the pH increases above 9.6, hydroxyl alkalinity (due to the presence of the hydroxide ion) starts to occur.
