Titration Curves
(...but wait, there's more)
-----------------------------------------------------------
Learning Goals
- Solve titration equivalence point problems using the shortcut.
- Explain why the pH at the equivalence point is:
- neutral for strong acid/strong base.
- basic for weak acid vs. strong base.
- acidic for weak base vs. strong acid
- Explain that weak acids and strong acids require the same amount of base to be neutralized because the weak acids will dissociate during neutralization.
- Determine the equivalence point (stoichiometric point) of a titration by looking at a titration curve.
- Determine the pKa of the weak acid being titrated using a titration curve.
- Do the eight calculations that will allow a sketch for the pH curve for a weak acid or weak base using ICEE/H-H and BRA:
- Bell Ringer
- Get calculators, paper and copy of pics. You will need a pencil and maybe some colored pencils, highlighters...
- 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.

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.
