Identify the correct statement:

\(CrO\) is basic, \(Cr_2O_3\) is amphoteric, \(CrO_3\) is acidic

The correct statement is: (3) \(CrO\) is basic, \(Cr_2O_3\) is amphoteric, \(CrO_3\) is acidic

Here is an explanation for each compound:
\(CrO\) (Chromium(II) oxide) is a basic oxide because it contains chromium in the +2 oxidation state, and oxides of metals in lower oxidation states tend to be basic.
\(Cr_2O_3\) (Chromium(III) oxide) is amphoteric because it can exhibit both acidic and basic behavior. It can react with both acids and bases, making it amphoteric.
\(CrO_3\) (Chromium(VI) oxide) is acidic because it contains chromium in the +6 oxidation state, and oxides of metals in higher oxidation states tend to be acidic.

So, option (3) correctly describes the acidity/basicity properties of these chromium compounds.
