we took melting points of the crude C18O3H16 we made two weeks ago.

Well, the 6000 cm3 flask was not enough large, so I am doing some bucket chemistry…
Acid hydrolysis of the reaction mixture with acetic acid in an ice bath cooled overhead stirred HDPE bucket.

I did it! I learnt them all! And pretty easily actually. All the polyatomic cations and anions woohoo! Hopefully writing chemical equations will be a hell of a lot easier for me now, as that is what I was struggling with… knowing the charge of certain compounds of ions. But now that I know them all, wahay! Here’s to future chem! Learning the monatomic ones tomorrow - which should be super easy because they’re all singular elements/atoms anyway!

Drying our extracted compound on a vacuum after a diazonium coupling reaction.

The first picture shows the solid beginning to show cracks after 15 minutes of drying on vacuum on the Buchner funnel. The second picture is after 45 minutes of drying and the solid now has widespread cracks.

These cracks are called "desiccation cracks" and are normally seen in dried mud. They form due to a solid thoroughly drying out, which causes contraction and thus the solid ‘cracks’.
