SOLUBILITY & COMMON IONS!

Today class we went over the rest of the Chemical Equilibrium booklet that Ms. K handed out last weeek, started from page 3. We did the examples 4 and 5 for "Solubility" and examples 1, 2, and 3 for "Common Ions"! So for those who weren't in class, Ms. K had posted the steps of the solutions in the slide show below. It's pretty much about finding the Ksp and the concentrations of each ion, but in different cases, where we might have initial concentration for one of the ion. And if you have any questions, or dont understand the steps, please ask Ms. K?!?! Other than that, the test has moved to Tuesday, which is yay for those who are lazy to study in the weekend! And that's about it. Homework will be Assignment # 3, question from 1-3!

And the next scribe will be keith!!

Test Tube Mystery Lab

Hi guys, I'm the scribe for today's class since i wasn't there on Friday. We started to work on the test tube mystery lab, which we have to identify the 12 unknown solutions that are given in the hand-out we got last week from Ms. K. It tells us what we have to do before starting the lab, what materials we need for the lab and from what we have learned from the past 2, 3 weeks, we should know how to observe it. We also can go on the net to find out or get more information for the lab. Each group only have to hand in one lab write-up explaining how you determined the identity of each test tube, also include the observations (any precipitates formed) with the net ionic equations. Anyways we'll also have tomorrow to finish the lab. Goodluck everyone! :)

The next scribe will be crystal.
