Is CaO an alkali or a base? | Socratic
Metal oxides are basic, non-metal oxides are acidic. Now, we need to check if it''s soluble or not, as if it is soluble, it''s considered an alkali, but if it''s insoluble, it is a base. The solubility rule states that for oxides and hydroxides, most are insoluble, with the exceptions of sodium, potassium, and more.
Magnesium and calcium were once thought to be the same substance. In 1755 Scottish chemist Joseph Black showed by experiment that the two were different. Black wrote: “We have already shewn by experiment, that magnesia alba [magnesium carbonate] is a
