Thurs-Day 2
AP Chem - spent another entire period on kinetic explanation of shifts in solubility equilibria for sparingly soluble salts (we have a major quantitative unit coming up on this!)
We saw that, with some less than obvious stresses, that either more precipitate can be formed or more precipitate can be dissolved. We also saw that diluting a saturated solution with water would undissolve (net) more salt with the net result of unchanging ion concentrations in solution at the new saturation point i.e. dilution does NOT change Ksp.
Bio - we looked at the lymphatic system, its structures and functions, and its relationship to intercellular fluid, and to the circulatory system.
We then reviewed for tomorrow's Regulation via the Immune System exam.
