WebApr 5, 2024 · Supersaturation is a metastable condition, and sometimes, the solution can be brought back to equilibrium, to saturation, by scratching the sides of the flask, or … WebAfter explaining the concepts of saturation, supersaturation, crystallization, and seed crystals, pour the supersaturated solution into a petri dish on the overhead projector stage to a depth of no more than 1/4". Add one or more seed crystals of sodium acetate trihydrate to the saturated solution. Needle shaped crystals will start to grow slowly.
Webdirectly from your hot water bath by pipet. In this example of “super-saturation” (review prelab intro), visible crystals/cloud-point will not appear. After the 3 pipets of water (~50% water), don’t add anymore. (In general, if you’ve added 50% water and still haven’t seen visible saturation, assume you have super-saturation WebCrystallization generally occurs by reducing the solubility of a solute in a solution by one or a combination of these four methods. When solubility is reduced, the solution will become supersaturated. Supersaturation is the driving force for crystal nucleation and growth.
