The three reactions below are all at equilbrium simultaneously in solution.

Ca2+(aq) + C2O42-(aq) = CaC2O4(s)

H2C2O4(aq) = H+(aq) + HC2O4-(aq)

HC2O4-(aq) = H+(aq) + C2O42-(aq)

If sodium hydroxide is added to this solution, would you expect to see more or less of the precipitate (CaC2O4) formed in the solution? Explain your reasoning by showign the effect of the addition of sodium hydroxided on the equilibrium for the reaction.

Concept: During the first week of this project, you need to synthesize several common kidney stones by precipitation reactions (Make sure that you save the kidney stones for week 2). You need to choose the reactants in a way that the kidney stone is the only product that precipitates out from the solution, while all other products remain soluble in water. This way the precipitate (kidney stone) can be separated from the rest of the solution by either filtration or...
