Webb30 dec. 2013 · For an organic compound, it is relatively safe to assume that it will dissolve better in the organic layer than in most aqueous solutions unless it has been converted to an ionic specie, which makes it more water-soluble. WebbOnce the bottom layer is drained out the bottom, the top layer is often poured out the top opening. This prevents the top layer from being drained through the area where remnants of the bottom layer can re-mix with your newly separated top layer. Finishing the lab: Once the acidic compounds have been separated as salts, they can be converted ...
