Lab Fails: Part 2
Yesterday in class, we participated in the formula or a chloride lab. However, this so the second lab this week that has gone horribly bad for me. We were suppose to heat zinc and HCl to evaporate the water in order to determine the formula for zinc chloride. We didn't get this far though because as we were heating our mixture, it began to foam which we later found out was due to the foul before us rinsing out the beaker improperly, so there was still soap in it. We had to restart, and the same thing happened again, so we restarted for a 3rd time but after the first 2 failed attempts, we didn't have time to finish. Fortunately, Ms. Frenkenberg was kind enough to give us some data to use. Below are some pictures of the lab and calculations with the days we were given.

Shaneerah, this post was very funny to me, but was also educational. Thanks for sharing your experience, so now others know how to detect small problems like this in their experiments. Maybe next time it would be helpful to walk through the measurements of how much zinc and liquid to put in so the experiment is easier to replicate! It would go well with your great videos you added. Overall, great work on your post!
