This lab is very similar to the Percent acid in vinegar lab, except we were to write our own procedure and given a little bit of a different task. As you can probably guess from the title, we are to find the molar mass of an unknown acid. This means more fancy titrations and for my group, re-standardizing and practically starting all over. Its totally cool though because I enjoy titrations.
We had this fancy way of stirring our water with our unknown acid. It was a small stir rod dropped in the flask, while the flask was sitting on a hot plate. A magnet in the hotplate caused the stir rod to spin which helped us dissolve our solution, along with the heat from the hot plate.
(There was a video, but I don't know how to do cool internet stuff so you can see it... I'm sorry. I hope that the description is enough... or the fact that you also participated in the lab)

ReplyDeleteThe math for this one was a little different too, and I need to shout out to you because you really helped me out with it. Also, I likie the way you rearangeed you blog. It looks nice. Did you notice that the mystery substance smelled like nail polish remover? Because I certainly did, it was interesting. Anyway, here's to a low percent error and a high percent on the test tomorrow.
