PH for the solution which contain CO

PH of a solution which contain CO is less than 7.

Explanation:

Carbon monoxide (CO) is a non metallic oxide as carbon is a non-metal. Metallic and non metallic oxides differ in terms of their acidic or basic nature. Metallic oxides are usually basic in nature whereas on metallic oxides have acidic nature. Carbon monoxide CO has a slight acidic nature. Hence its PH value will be less than 7. In the PH scale, 7 corresponds to neutral nature while values less than 7 indicate acidic nature and values greater than 7 indicate basic nature.
