When this song came out I damn near lost it. Kasane Teto and science are two of my favorite things in the world, and they are even better when paired together!!

I'm gonna start uploading my USTs more often, so be sure to check out my youtube descriptions if you want to download them!

Ah, you were wondering about the chemistry performed by Teto? Well, this is what is called an “electrochemical synthesis”. By letting an electrical current flow through an anode and a cathode submerged in a solution, you can trigger an oxidation-reaction at the anode and a reduction-reaction at the cathode. In this case, we have a solution of hydrogen chloride, acetonitrile and triphenylphosphine. By hanging a piece of cobalt on one of the electrodes, we can then create cobalt(II) ions which will react with the chloride ions from the hydrochloric acid. Almost immediately upon turning on the current, we will see the solution start to turn into a beautiful vibrant blue color! This happens when the newly formed tetrachlorocobaltate(II) ionic complexes unite with the triphenylphosphine. The product is a salt, a compound held together by strong ionic bonds, with the chemical formula ((C6H5)3PH)2CoCl4.

However, we don’t want our final product to be dissolved in acetonitrile. The next step is to evaporate the organic solvent. We do this by using a so-called rotary evaporator, or “rotovap”! By applying gentle heat from the basin filled with water, and gradually lowering the pressure inside the flask containing our product to create a vacuum, we can quickly evaporate the solvent until almost no liquid remains.

But, the rotovap is not enough. The final step required for obtaining a sample which purely consists of the desired product is a suction filtration. We place the sample on top of a piece of filter paper in a Büchner funnel, a ceramic funnel with holes at the bottom. We then place the Büchner funnel in a Büchner flask and connect it to a water tap with a rubber hose. When the water is turned on, a vacuum is created by the water aspirator. The water does so by pulling some of the air in the tube with it, generating a vacuum. By rinsing the product with diethyl ether, an organic solvent in which our product can’t be dissolved, we make sure that any remaining impurities are washed away, and that our sample is dry. Now that we have our dry, clean crystals, we may weigh them to calculate our yield, and then place them in a transparent container to admire our hard work.

Why was this particular chemical reaction picked to be illustrated? Well, the compound itself doesn’t have any exciting applications. But the color sort of reminds you of a leek-loving diva, does it not? :3
