Consider the reaction of "carbonic acid", which we think of as a mixture of carbon dioxide and water:
[CO2(g)+H2O()][H2CO3] H+(aq) + HCO3-
where Ka for this reaction is 4.4x10-7 (we ignore the second ionization, which is negligible). What is the concentration of HCO3-(aq) for an 0.00621 molar solution of "carbonic acid"?
