Carbon dioxide is more soluble in alkaline water. Why?

alkaline water contain calcium and sodium ions as well as hydroxyle ions and if CO2 gas is pass through such water the soluble ions react with CO2 to produce carbonates and bicarbonates ion and further passing of CO2 will increase the concentration of carbonates ions and they will react back with sodium and calcium to form their carbonates. read more

Carbon dioxide molecules must first pass the air and water barrier to dissolve in water. Once CO2 crosses the water’s surface, the molecules gain a shell of water molecules and transfer from carbon dioxide gas, or CO2(g), to carbon dioxide in an aqueous solution, or CO2(aq). read more

The carbon dioxide gas is dissolved in the soft drink and forms an equilibrium with water, forming carbonic acid. this process is exothermic. When equilibirum reactions are exposed to changes in temperature, pressure and volume the equilibrium shifts in such a way to minimise that disturbance. read more

The carbon dioxide combines with a water molecule to form carbonic acid. In a basic environment, the carbonic acid molecule breaks up into a two hydrogen cations and a carbonate anion. Hydroxyl anions from the sodium hydroxide bond with the hydrogen cations forming water. read more

Once CO2 crosses the water’s surface, the molecules gain a shell of water molecules and transfer from carbon dioxide gas, or CO2(g), to carbon dioxide in an aqueous solution, or CO2(aq). This process is very slow. read more
