The experiment is going to be a Doc-Ott-Original (be afraid!) that will be a cross between (I think) The experiment you did earlier (Acid in soda, see below) and sample exercise 16.10 on page 682 of your text.
Prelab questions are simply 16.54 and 16.64 of your textbook.

RQ8 is the biggie right before Spring break. There will be no lecture that day, just the 50+ point quiz. This guide might change a little bit, depending on how far we get next week, but stuff will simply be ‘added’ to what is below.
It will be roughly 25 points from the ‘past’ (phase I) and roughly 25 points from equilibrium land.
From phase 1 problem set
5, 12, 34, 47, 58, 79, 89, 93, 97, 126, 131, 149, 167, 185
from equilibrium phase problem set
1-116
This might help with what we talked about Tues (and will finish discussing wed)
As I told you this week in lab, one of my goals is to slowly find websites that explain concepts both well and different from the way I teach. I am looking for short, sweet, to the point types of explanations, not just online text (read: LONG boring) versions.
With that in mind, I give you just such a set, three (each short) pages introducing equilibrium. I would love to hear any comments you have in these links, good, bad, or indifferent.
Equilibrium pt 1 Pt 2 Pt 3
Grades have been posted, follow the ‘document reference’ link over there on the righ hand side….
If you would like me to respond to e-mail, you need to have a little bit of etiquette. The most obvious is to indicate who you are. I do not memorize your email address, so I cannot recognize thedudeman99@whatever.com as you. Pretend this like a semi formal letter. All you have to do in mention your name.
Some professionalism is appropriate. I am not your buddy who you send email jokes too. I am your college chemistry professor. No need to send me some cool chemistry joke you got from a friend. Trust me, I saw it long before you did.
I just thought of this recently. Consider it a good ‘procedure’ for doing any type of equilibrium calculation.
1. What is in the system?
2. What does it do? Write the appropriate equilbrium equation and K expression.
3. What are the initial conditions? If you don’t know them, pick a variable.
4. Which way did it shift, by how much?
5. What are the final conditions? What do you know about them?
6. Answer the question posed.
I was surfing around and found a bunch of good questions, that are complete with worked out (and explained) solutions.

Why should I make screencasts if you have sites like this?
