Fri-Day 2
Physics - took the written-response part of the Waves 2 exam
AP Chem - finished up our Ksp equilibrium unit.
We completely explained the increase in solubility of all salts with increasing hydronium ion concentration; the ONLY exceptions are salts of conjugate bases of 5 of the strong acids : chlorides, bromides, iodides, nitrates, and perchlorates.
We explained each of the parts of a selective precipitation problem, determining the concentration of ions from a less soluble salt that remains when the more soluble salt is just at the saturation/precipitation point.
