Friday, April 4, 2008 - 4A

Handed back and went over any questions on Chapter 2 test. Recollected tests.

Students did Fractional Distillation Lab Day 1.
1. Take data every 30 seconds
2. Everyone plots the data on graph paper
3a. On graph, clearly indicate the boiling points and show the BP temperature
b. For each section of the graph, clearly show where you have alcohol, water, or a mixture.
c. Show swap temperatures on the graph.
4. In notebooks, write down the material list for the fractional distillation labs.

Each student came up with their large test tube, put in 3-5 boiling chips, and I gave them approx 25 mL of solution.

Stop boiling when you have 1 - 1.5 cm left in boiling test tube.

Pour all liquids in designated beaker, nothing goes down sink.

Students did a great job of setting up and getting going. I was very proud of all of them.
