Day 161

Continuing our discussion from Friday on solubility, we worked on understanding and using solubility curve graphs in order to determine solubility at a given temperature, the saturated/unsaturated/supersaturated nature of the solution, and the amount of undissolved solute that would be found at the bottom of a container housing a supersaturated solution that's been disturbed. (Pause for a deep breath....)  Following an in-class sheet of questions to reinforce these concepts, a packet for tomorrow's lab activity was distributed; the Pre-Lab Questions may be turned in prior to the start of tomorrow's lab for extra credit, so logn as they are neat, legible, and on non-notebook fuzzied paper.  Required homework for smooth running and greater chance of success in the lab tomorrow is to read the packet (and wear appropriate shoes...).

The clip below will give you an idea of the sort of phenomena you are watching for to determine when you have hit the saturation temperature for your sample(s):
