the hardness of water causes the disolved Ca+2 ion form magnesium carbonate, Mg CO3 which is slightly doluble solids. soaking solid magnesium carbonate in water only yeilds small amounts of free calcium ion that can be captured but still solvated using a chelating milecule called Ethylendiamineteraacetic acid or EDTA. the 2 reactions involved: 1- Mg CO3 ➡ Mg^+2 + CO^-2 keq= 6.8×10^-6 2- Mg^+2 + EDTA ^-4 ➡ MgEDTA ^-2 + CO ^-2 keq= 4.90×10^8 these reactions combine to give...

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?
