Editing Potassium (section)

===Chemical===
Potassium reacts with oxygen, water, and carbon dioxide components in air. With oxygen it forms [[potassium peroxide]]. With water potassium forms [[potassium hydroxide]] (KOH). The reaction of potassium with water can be violently [[exothermic]], especially since the coproduced [[hydrogen]] gas can ignite. Because of this, potassium and the liquid sodium-potassium ([[NaK]]) alloy are potent [[desiccant]]s, although they are no longer used as such.<ref>{{cite journal|doi=10.1021/jo101589h|pmid=20945830|title=Drying of Organic Solvents: Quantitative Evaluation of the Efficiency of Several Desiccants|journal=The Journal of Organic Chemistry|volume=75|issue=24|pages=8351–8354|year=2010|last1=Williams|first1=D.
