Check out “Beautiful Chemistry,” particularly the reactions section. You’ve never seen precipitation, metal displacement and crystallization like that — recoded in 4K UltraHD, zoomed in, sped up, and soundtracked with soft porn music and delicate house. Watch the teaser reel above and see a few of them separated, with excerpted context.
The reaction occurred when a piece of metal salt was dropped in water glass (water solution of sodium silicate, Na2SiO3). The salt began to grow and generate many interesting forms due to the formation of water-permeable metal silicate membranes and osmotic effects.
Crystals are beautiful, both externally at the macroscopic level and internally at the atomic level. The same is true for the process of crystallization, which is the formation and growth of crystals. This video shows the crystallization of copper sulfate (CuSO4), sodium thiosulfate (Na2S2O3), potassium ferrioxalate (K3[Fe(C2O4)3]), and sodium acetate (CH3COONa). More accurately, these crystals all have water molecules inside them. Their chemical formulas are CuSO4·5H2O, Na2S2O3·5H2O, K3[Fe(C2O4)3]·3H2O, and CH3COONa·3H2O.
The molecules inside some plants giving them vibrant colors can change to other colors under acid and base conditions. What we show here is color change of purple cabbage and a flower named Teornia fournieri in sodium hydroxide (NaOH) and hydrochloric acid (HCl) solutions.
We mixed the oily chemicals inside fluorescent sticks, then added sodium hydroxide (NaOH) solution to the mixture, which was inspired by Mr. Theodore Gray’s Mad Science 2. What we got was something interesting: colorful fluorescent droplets with dynamic movement.
