Do serial dilutions start out as saturated solutions?, Meaning when it starts out ppt forms, but there is a point where ppt stops forming, so when the ppt stops forming does that mean it is representing a saturated solution, and that when the ppt is not forming the solution has not dissolved as much solute as it could, and from that point on it can not dissolve anymore?

The first sentence ending with the question mark makes sense. The rest does not. The answer to the first sentence is No, serial dilution may start at any concn one chooses.

Ok, so when doing a serial dilution, would you day that the first well with no ppt represents a perfectly saturated solution, why or why not?

In general, no. In whatever sense you're talking about, perhaps. I'm trying not to buy a pig in a poke here.

Serial dilutions do not start out as saturated solutions. In fact, the purpose of serial dilutions is to decrease the concentration of a solute in a solution.

To perform a serial dilution, you start with a concentrated solution (also known as the stock solution) and add a specific volume of this stock solution to a new container. Then, additional solvent (usually water or a suitable diluent) is added to achieve a desired final volume. This process is repeated multiple times, resulting in a series of solutions with decreasing concentrations.

Each dilution in the series is less concentrated than the previous one, but none of them are saturated solutions. In a saturated solution, the solvent has already dissolved the maximum amount of solute possible under the given conditions, resulting in the formation of a precipitate (ppt).

When the formation of a precipitate stops during serial dilution, it indicates that the concentration of the solute has reached a level where further dilution does not exceed the solubility limit. At this point, the solution is still not saturated, but it has reached a point where no additional solute can dissolve in the given solvent at the given conditions.
