Metal oxides are basic

Metal oxides are basic; they react with water to form bases such as hydroxides.

Metal oxides are basic reating with water the produce bases such as hydroxides
Metal and ox hides (oxides) make bass drums (bases).


E.g. sodium oxide + water → sodium hydroxide

Na2O + H2O → 2NaOH


Other examples of metal oxides include potassium oxide K2O and calcium oxide CaO.

Non-metal oxides are acidic

Because metal oxides are basic, non-metal oxides are acidic. They react with water to form acids.

E.g. carbon dioxide + water → carbonic acid

CO2 + H2O → H2CO3
