Typically, we think of precipitation as the stuff that comes from clouds: rain, snow, and everything in between. But, in chemistry lingo, precipitation is used to describe the creation of a solid from a liquid. The concept alone is pretty cool, but its applications—like making pigments and desalinating water as part of water treatment—are even more fascinating. It’s particularly useful in purification processes.
If you didn’t pay attention in chemistry, the video below will make you wish you did. Shot by Yan Liang using a macro lens, the short film showcases six precipitation reactions in stunning slow-motion and with precise detail. Chemicals swirl like smoke, slowing down only to congeal into a solid mass. Scroll down to enlighten yourself.
