Summary[edit]

Description
English: A reaction of potassium metal with water. Hydrogen is liberated that burns with a pink/lilac flame, the flame color owing to burning potassium vapour. Strongly alkaline potassium hydroxide is formed in solution.
Deutsch: Reaktion des Alkalimetalls Kalium mit Wasser. Bei der exothermen Reaktion wird Wasserstoffgas (H2) freigesetzt, das sich unter Anwesenheit von Luftsauerstoff aufgrund der Wärmeentwicklung selbst entzündet. Die rötliche Färbung der Flamme geht auf verbrennenden Kaliumdampf zurück. Ferner entsteht bei dieser Reaktion stark basisches Kaliumhydroxid (KOH), das in Lösung geht.
Bahasa Indonesia: Reaksi logam kalium dengan air. Hidrogen dibebaskan yang terbakar dengan nyala api merah muda/ungu muda, warna nyala api karena membakar uap kalium. Basa kuat kalium hidroksida terbentuk dalam larutan
