Ochsner+iLab

Monday January 25, 2010 Dr. Simpson's Honors Chemistry class visited iLab at Ochsner to conduct a distillation.

Choose one of the questions to answer below.

1. What safety features of the lab did you observe? There were many safety features used during the lab at Ochsner. The lab had fire safety objects and also a fume hoods that not only filtered air into the room and out. The students also used goggles and aprons to protect themselves from splash damage. -Rene I observed many different safety symbols and signs in the lab room. During the lab itself, we had to use goggles and aprons. This was so we wouldn't get any chemicals or liquids on our body and/or clothing. Anyone with long hair had to pull their hair back so the liquids wouldn't get into their hair. ---Brianna <3

2. What equipment was used?

Equipment used includes Erlenmeyer flask, hot plate, ring stand, condenser, fume hood, watch glass, matches, and a box filled with ice and beaker.

3. How was the composition of the distillate determined?

Tyler - We tested its flammability, the methanol is flammable but the water is not. We also added cobalt chloride to the distillate and to the original mixture but there was no difference.

4. How did this lab affect learning of chemistry concepts? We learned how to set up a distillation apparatus to separate a mixture based on physical properties - the two parts boiled at different temperatures.
