Chemistry - Alkalis vs Acids Watch
but what if a compound does not have H+ ions or OH- ions? Would they just be neutral?
I thought calcium oxide was alkali but how could it be alkali without having OH- ions?
As the above poster has said CaO is a base not an alkali as alkalis are soluble bases
Example: In the limestone cycle:
Calcium Oxide (CaO) and Calcium hydroxide (Ca(OH)2) are both bases and can be used to neutralise acidic lakes etc.
