Question

$H_{2}O$, $NO$, $CO$ are neutral oxides.

• A. True
• B. False

Answer 1

The correct option is A True

$H_{2}O$, NO, CO are neutral oxides. They neither turn moist red litmus paper blue nor turn moist blue litmus paper red. For pure water, $H^{+}=O{H}^{-}={10}^{-7}M$.

Note: Although CO has no acidic or basic properties (in terms of proton), it can behave as a Lewis base (electron pair donor) and thus forms complexes with transition metals (mostly with zero oxidation state).
