Mon-Day 1
Physics - we reviewed the Magnetism unit test; we then finished our magnetic field lines lab.
We reviewed the various properties/characteristics of waves, and then did the common calculations involving them, relating wavelength to frequency to period to speed of the waves. We also related the speed of a wave to the distance that a given part of the wave travels in a given amount of time
(d = v t).

AP Chem - we did another permutation of weak acid equilibria; this time, the pH and initial concentration of the acid is given; from that, we determined the Ka, and the percent ionization.
A single pH reading from a known concentration is sufficient to determine the Ka of any acid at a given temperature.
There is just one more permutation in which you will be given the Ka, and the equilibrium pH to determine the initial concentration of the acid.
We then applied the same process to weak bases i.e. ammonia and their derivatives, which we will continue tomorrow.# posted by C @ 1:10 PM
