Today’s labs were quite interesting. We were able to work with magnetite, whose chemical compound is Fe3O4. We formed this by using both Ferric and Ferrous ions combined with three hydroxide ions, forming a FeO(OH) compound which combined with tetramethylammonium hydroxide. This made me realize that nucleation reactions can occur unexpectedly and spontaneously without any added energy. I recall doing precipitate labs in AP Chemistry class, but none of them were able to be magnets and attach to other magnets at bottom surfaces. Usually they just make cool colours like yellow chromate solids or others involving transition metals, such as the specific oxidation states involved in the solid. They generally have a Ksp of a very low number when bonded to oxygen or hydroxide anions, because hydroxide is not at all soluble with anything besides 1A alkali metals, which are soluble with everything, and of course ammonium salts. Photolithography was very interesting as well, because the UV rays can give copper covered by a protection paper an amazing effect with transparencies. Also, the Look Around You inspired me to research my ancestors’ pasts, and maybe see if there are any available spirits to see and carry out experiments with gigantic machines that contain a thousand buttons each which have unknown functions. Also, I will note in my copybook that not all ghosts are cooperative, despite past procedures that affirm otherwise.
