CO2 dissolved in wastewater will form carbonic acid (a weak acid), which in turn reacts with caustic wastes to neutralize the excess alkalinity as follows: 27. CO2 + H2O → H2CO3, flue gas wastewater carbonic acid H2CO3 + 2NaOH → Na2CO3 + 2H2O, carbonic acid caustic soda in wastewater soda ashash H2CO3 + Na2CO3 → 2NaHCO3 + H2O.
