A solution contains 0.1M total carbonate (H2CO3 + HCO3- + CO3=). If the pH is 6, find the concentration (approximations permitted) of each carbonate species present. Refer to the figure carbonate species in the Acids and Bases notes labeled "Predominance Diagrams" and the Table of Ionization Constants in the same notes when arriving at your answer. If the solution also contains 10-4M Ca++, is it saturated, unsaturated, or supersaturated with respect to calcite?
