Why is it preferable to use a metal ion buffer to achieve pM equals 7 rather than just dissolving enough M to give a 10 to the negative 7 M solution?
Soccerchicka407
A metal ion buffer maintain the desired (small) concentration of metal ion from a large reservoir of metal complex (ML) and free ligand(L). If you trtied to dissolve 10^-8 M metal ion in most solutions or containers, the metal would probably bind to the container wall of to an impurity in the solution and be lost.

How could you compare a saturated solution to an unsaturated solution?
In a saturated solution, if you add any more of the substance that the solution is saturated with, it will either not dissolve or cause some of the existing solute to precipitate or separate. The one caveat is that it is possible to achieve a "supersaturated solution" by careful manipulation of a solution to bring it into a metastable state. One common way to achieve supersaturation is to cool a saturated solution in a container which is so smooth that it lacks nucleation sites.
