Calculate [CO₃^2-] in a 0.010-M solution of CO₂ in water (usually written as H₂CO₃). If all the CO₃^2- in this solution comes from the reaction

what percentage of the H⁺ ions in the solution is a result of the dissociation of HCO₃^-? When acid is added to a solution of sodium hydrogen carbonate (NaHCO₃), vigorous bubbling occurs. How is this reaction related to the existence of carbonic acid (H₂CO₃) molecules in aqueous solution?
