Prelab Rainbow Lab

  1.  Go over WS multiple choice answers.  Any Q’s?
  2. Demo:  H+   +   P-   <—->   HP where P- is pink and HP is colorless.  You have HCl, NaOH, and NaCl.  What would happen if you added each to the equilibrium?
  3. Do:  Prelab for the Rainbow Lab.  Using the prelab handout, predict what would happen when you add each of the solutions.  Decide as a group which reactions you will do in order to make the 7 colors of the rainbow.
  4. If time, hand back Unit 1 tests and the test analysis and corrections.
