@swagsperimentalist: Anhydrous cobalt (ii) chloride (CoCl2) is blue. I only have the purple hexahydrate, but by adding LiCl to CoCl2•6H2O, we can strip off some of the water and afford a pleasant blue color. What else do we see? #Science #stem #chemistry #physics #microscope #wetenschap #systemschemistry #scheikunde #химия #наука #lithium #cobalt #experiment #deliquescence #satisfying #oddlysatisfying #swagsperiment
