8.5: Extraction Theory When a solution is placed in a separatory funnel and shaken with an immiscible solvent, solutes often dissolve in part into both layers. The components are said to "partition" between the two layers, or "distribute themselves" between the two layers. When equilibrium has established, the ratio of concentration of solute ...

First Few Hours: Bleeding is steady but should slow down with gauze pressure. 6–12 Hours: Blood should stop flowing freely, and a clot should form. 12–24 Hours: Light oozing is normal, but active bleeding should stop. After 24 Hours: The socket should remain covered by a clot with little to no fresh bleeding.
