                                  Big Ideas
                                  • Big Idea 3:  Changes in matter involve the rearrangement and/or reorganization of atoms and/or the transfer of electrons.
                                  • Big Idea 6:  Any bond or intermolecular attraction that can be formed can be broken. These two processes are in a dynamic competition, sensitive to initial conditions and external perturbations.

                                                                                                                                                4. Determine the equivalence point (stoichiometric point) of a titration by looking at a titration curve.

Pick up a set of six handouts for today and your U10 I Can if you don't have one.  Sorry for all of the copies.  I actually didn't mean too.

These two processes are in a dynamic competition, sensitive to initial conditions and external perturbations.
