Thurs-Day 1
Physics- took the unit exam on Magnetism; we then worked on the magnetic field lines lab questions.
We then began weak acid equilibria problems; we listed the possible variables, and determined the pH of a weak acid for a given initial concentration.
AP Chem - finished Bronsted-acid reactions in which we predict the "favored" direction as equilibrium is established; this time, we started the problems with either the Ka's of the acids, or Kb's of the bases, or we began with the pKa's of the acids, etc.
Remember the HIGHER the pKa (or pKb) the WEAKER the substance is at its function.
