This Monday, we took a pre-lab quiz in order to participate in the Formula of a Hydrate lab. My partner, Kendall Kellerman, and I both managed to pass it and carry out the lab. To start it off, we put some crystallized hydrate into a test tube and recorded its mass. Next, we turned on the bunsen burner and held the flame up to the tube until almost all of the water in the hydrate had evaporated and it had turned white. Then, we recorded the new mass. While doing this lab, I learned a couple things:
1. Adding water back in to the anhydride is really cool looking, and it produces heat.
2. DO NOT ADD WATER BACK IN TO THE ANHYDRIDE. It becomes too hot to hold, and is almost impossible to get out of the test tube. Kendall and I know this from experience....
Here is the hydrate when we added the water back to it:
After completing the lab, I wanted to learn some more about how this whole process worked, so I found this website:
Dehydrating a Hydrate
This post perfectly explains our experience with the lab and everything that we had to do. I completely agree with everything that you said, and the websites that you included were actually pretty cool and helpful. I wish we wouldve known about your last bullet before we did the lab, but I guess someone had to learn the hard way.
ReplyDeleteCarly, thanks for the video and tips! I found the video very educational and it helped me learn more about the entire process of our lab. Sadly, we did not receive your tip early enough, and our group ended up adding water to our anhydrate, making it difficult to get it out of the test tube. However, now we know for next time. Great post!
ReplyDeleteVery informative link, thanks for the website, and great post and warning.
ReplyDeleteYour comment about adding water made me giggle. It was funny because if me and Bri would not have seen you guys do this, we would have done the same exact thing. The website you included was interesting as well. Thank you!
ReplyDeleteCarly, your video was very helpful as to how the experiment was supposed to go, and it helped me understand the process to carry out for the lab more. Your comments did make me laugh though that you turned it back blue, and now I know not to do this in my lab if we are to do it any other time. Nice post!
ReplyDeleteThis is a really useful post because it explains the lab in excellent detail along with providing a great link that helps with comprehending the lab. Also, the hydrate looks awesome after water is added back into it even if you aren't supposed to rehydrate it!

ReplyDeleteThank you for your insight about how this lab works. I too made the mistake of adding water and felt an exothermic reaction happen extremely fast! I loved the picture you posted because it really helped me visualize what you were describing! Thank you for this awesome post!
