Fri-Day 1
Physics - we finished up our Properties of Waves lab, showing the effect of reflection and transmission of a wave from one medium to another. We then worked on the Waves 2 questions in the packet.
AP Chem - we did the final permutations of acidic and basic salt problems; there is an additional problem posted in the notes in which the pKb of a base from a basic salt is determined, given the pH of a certain concentration of the salt. Finished the acids/bases by completing the acidic salt question and doing a basic salt problem; it is important to not only know the mechanics of solving these problems, but also knowing how and why a given salt is acidic or basic by drawing the reaction that is going on with water in the solution container.
