Chapter 5, Problem 5.4E

Supersaturated solutions can be made in which more solute is dissolved in solution than would normally dissolve.

These solutions are inherently unstable, however. A seed crystal of calcium acetate, $\text{Ca}{\left({\text{C}}_{\text{2}}{\text{H}}_{\text{3}}{\text{O}}_{\text{2}}\right)}_{\text{2}}$, precipitates the excess solute from a supersaturated solution of calcium acetate. When the excess solute has finished precipitating, a chemical equilibrium is established. Write the chemical equations for that equilibrium, and write the net chemical reaction that occurs overall.
