Many metals react with oxygen to form oxides.
Some ofthese oxides, such as Na 2 O, CaO, and SrO, react with water toform basic solutions. Many nonmetals can react with oxygen to form oxides as well. These nonmetal oxides, however, react with water to form acidic solutions. Thus they are called acid anhydrides. B. react with water to form a basic solution.
