What do lithium batteries, table salt and firework rockets have in common?
\nAll of them contain compounds of alkali metals. Alkali metals are members of the first group of the periodic table of the elements. The metals in this group are lithium, sodium, potassium, rubidium, caesium and francium.
\nThe word \u201calkali\u201c is derived from the Arab \u201cal-qalya\u201c for potash, the colloquial term for potassium carbonate. \u00a0
\nIn this film we want to take a closer look at the representatives of this family of elements, compare their properties, investigate the chemical behaviour and see where we encounter their chemical compounds in everyday life.
\nAlkali metals and alkaline solutions \u2013 also called basic solutions \u2013 are noxious for the skin. Therefore, additional protective gloves should be worn \u2013 apart from the obligatory protective goggles required in laboratory work.<\/p>\n","protected":false},"excerpt":{"rendered":"
