Chapter 13, Problem 110E

Calculate [CO₃²⁻] in a 0.010-M solution of CO₂ in water (usually written as H₂CO₃). If all the CO₃²⁻ in this solution comes from the reaction

${\text{HCO}}_{\text{3}}{}^{-}\left(aq\right)\rightleftharpoons {\text{H}}^{\text{+}}\left(aq\right)+{\text{CO}}_{\text{3}}{}^{2-}\left(aq\right)$

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?
