Chromatography

This important video shows the two types of chromatography that you are expected to understand: Paper chromatography and column chromatography.

The video uses Thin Layer Chromatography, TLC, which uses a thin layer of gel on a glass plate rather than paper as the stationary phase. Other than that, the procedure is identical to paper chromatography.

ChemToddler has a number of other excellent chemistry videos.

A video showing dipole-ion dissolving. View it a couple of times. Note which ions attract the oxygen end of the water molecules and which ions are cloaked by the hydrogens of a water molecule. Understand that the ion-ion bond is being broken as the dipole-ion intermolecular attractions are being formed. It takes quite a few water molecules to cloak a singe ion.

A Capella Science has put a video together that sums up much of what you have learned in Chapters 7,8,9,10,11, and 24 in 4 minutes and 44 seconds of song. You should understand 90% of it. The better you understand these chapters the more you'll see in the video.

The only major concept that we did not cover was molecular obitals which have the up down animations.

Molecular Shape of You goes from microscopic electrons, protons, atoms, molecules, and polymers to macroscopic you.
