2622: Alkaline & Basic: Why 2 Words Feb 19, 2022

Something that is an alkaline is described as being basic, but this is a totally different root. The reason that a substance's alkalinity is denoted as basic is because 'basic' is the more generic term; all alkalis are basic but not all bases are alkaline. A base will always neutralize an acid creating a salt and water but only alkalis, alkali metal hydroxide specifically, will dissolve in water. Though 'alkali' is only a specific term, originating from Arabic meaning 'the ashes' some of the meanings of 'base' have overlapped with it.
