Dioxygen directly reacts with nearly all metals annd non-metals except some metals (e.g., Au, Pt) and some noble gases and form oxide(s). Oxides can be simple (e.g., MgO, Al_(2)O_(3) ) or mixed (Pb_(3)O_(4),Fe_(3)O_(4)) . Simple oxides can be classified on the basic of their acidic, basic or amphoteric character. an oxide that combines with water to give an acid is termed acidic oxide (i.e., SO_(2),Cl_(2)O_(7),CO_(2),N_(2)O_(5) ). for example, SO_(2) combines with water to give H_(2)SO_(3) , an acid.
