Experiment 5: Extraction and Purification

The next week will be filled with extractions, recrystallizations, and even one synthesis!

Here are some resources to use!

A great post that sums up extractions.  Not everything is applicable, but it will give some good background on why we are doing certain things. Also, check out more of this blog! There’s stories of explosions, dead pigeons, and many hospital visits all while the author was under 18 in Communist-Poland.

What you don’t want to see…
Sublimation! (of ferrocene. your stuff should be white!)

Happy purifying!



Experiment 3: TLC

Awesome Students,

Here we come to our second way of determining purity of a substance /identifying what that substance is.*

TLC is extremely helpful and can be much faster than other ways of determining whether or not your product is pure or whether other side products have formed/starting material is still present.

Here’s some fun resources you can use!

Fun Video
Pretty Picture!
It may look ugly, but pure it is!

Another way to look at it.
An experiment at home!

A lovely almost-but-not-quite exhaustive look at TLC. Check out those charts!


Happy spotting!


*What do you think the first way is?

Experiment 1: Melting Point Determination/Calibration of Thermometer

Wonderful students,

The posts for each experiment will mostly be a gathering ground for resources on each topic, although this could also include important points I want you to remember from the lab lecture.

This experiment deals with measuring melting points using the MelTemp and calibrating your thermometer. The first two resources explain some of the concepts from the lab which will be useful in your discussion. The third resource will be helpful when making your calibration graph.

Happy Melting!



Welcome to Organic Chemistry Lab!

Hello all!

I’m very excited to have y’all in my lab this semester!

I will be trying this out as another form of communication to you during the semester where we can gather important notes, documents, resources, etc. Let me know how this is working for you or if you would like something else added!

Below are some important documents you should check out before the next lab session.



Happy Cooking!
