We had a substitute today and we did the LeChatelier's Principle Lab. Before the lab, we went over the answers to the pre-lab but they are not on moodle yet so if you need to see the answers you must wait until class tomorrow. All of the procedure and information for the lab can be found in the link above.
In the lab, we were able to see all of our recent work take effect in an actual reaction. We prepared 6 test tubes with Cobalt Chloride. We set A as the control tube and experimented with the others. To test tube B we added distilled water, which changed the color of the substance. It changed from blue to pink. This means that when H2O is added, the reaction moves to the left! I get excited about these things.
Here is the data Table:
| Test Tube | Final Color | |
| A | Clear Blue | |
| B | Pink | In Hot Water: Back to Blue |
| C | Light Blue | In Cold Water: Back to Pink |
| D | Thick Blue at Bottom | |
| E | Clear Purple | |
| F | Cloudy Pink |
Reminder to type the postlab for credit tomorrow. Don't forget the ICE problems!
