Webb1. CO2 Concentration in Water. The concentration of carbon dioxide (CO2) dissolved in water becomes a factor that affects pH. The reason is carbon dioxide triggers an increase in the concentration of hydrogen ions which makes the pH of the water decrease. That means when carbon dioxide is high, the pH of water automatically becomes acidic.
