With the exception of the lighter inert gases (helium [He], neon [Ne], argon [Ar], and krypton [Kr]), oxygen (O) forms at least one binary oxide with each of the elements. You can determine if a particular solution is acidic or basic by testing with an acid-base indicator. Answer: The chemical property which can be used to distinguish between a metal and a nonmetal is the formation of positive ions by metals. It is not either an acid or a base. We observed that the solution of oxide turns the blue litmus red which shows that the solution is acidic in nature. Most metal oxides are basic oxides and dissolve in water to form metal hydroxides: Na 2 O (s) + H 2 O (l) → 2 NaOH (aq) CaO (s) + H 2 O (l) → Ca (OH) 2 (aq) Acidic oxides are formed when a non-metal reacts with oxygen.
