Never trust an atom, they make up everything

Gravimetric Analysis of a Metal Carbonate Lab

October 29, 2013 by rachel · 1 Comment · Uncategorized

This lab was the first of many labs I hope to complete in this class. The main idea of this lab was to identify an unknown compound. Most of the steps were simple to follow, up until step 18. This step required precision a steady hand, and a little bit of luck. Luckily for us we had those in the form of Candace, the boys group however did not. After we finished the lab we were able to identify our substance as table salt, we also calculated our percent error. Ours was only .6% thanks to Candace the boys was much higher, but considering how many times they punctured and reapplied the filter paper it was still pretty low. I had fun with this lab, but I wish I participated more in the lab.  I look forward to doing many more labs in the future.
