Is there any reaction between carbon dioxide and sodium hydrogencarbonate solution?
My thought is that carbon dioxide, an acidic oxide , dissolve in water in the solution to form carbonic acid,so typical acid property will be shown, they react to form sodium carbonate ,carbon dioxide and water...

But,when i tried to write the equation CO2 can be cancelled,Does it mean that Sodium hydrogencarbonate itself,can decompose to form sodium carbonate + CO2+H2O?

[Borek]

CO₂ + H₂O H⁺ + HCO₃^-

or

CO₂ + H₂O H₂CO₃ H⁺ + HCO₃^-

(in practice these are indistinguishable as long as both steps are fast enough)
