Identify the reactants and products involved in the reaction. The reactants are carbonate ion (CO3^{2-}) and water (H2O). The products are bicarbonate ion (HCO3^{-}) and hydroxide ion (OH^{-}).
Recognize that this is an acid-base reaction where the carbonate ion acts as a base and water acts as an acid. The carbonate ion accepts a proton from water, forming bicarbonate ion and hydroxide ion.
Write the balanced chemical equation for the reaction: CO3^{2-} (aq) + H2O (l) \(\rightleftharpoons\) HCO3^{-} (aq) + OH^{-} (aq).
Understand that the reaction is reversible, as indicated by the double arrow (\(\rightleftharpoons\)), meaning it can proceed in both forward and reverse directions.
Consider the equilibrium state of the reaction, where the concentrations of reactants and products remain constant over time, and the reaction can shift depending on changes in conditions such as concentration, temperature, or pressure.
