\nWhen carbon dioxide (CO\u2082) dissolves in water (H\u2082O), it reacts to form carbonic acid (H\u2082CO\u2083) through a reversible reaction: CO\u2082 + H\u2082O \u21cc H\u2082CO\u2083. Carbonic acid is a weak acid that can dissociate into hydrogen ions (H\u207a) and bicarbonate ions (HCO\u2083\u207b), and further into hydrogen ions and carbonate ions (CO\u2083\u00b2\u207b). The presence of hydrogen ions increases the acidity of the solution.

\nNon-metal oxides that react with water form acidic solutions. CO\u2082 is an oxide of carbon, a non-metal. Other examples include SO\u2082 and NO\u2082, which form sulfurous\/sulfuric acid and nitrous\/nitric acid respectively, contributing to acid rain.
\n<\/section>\n
\nHydrogen (H\u2082), Nitrogen (N\u2082), and Oxygen (O\u2082) are diatomic gases that do not react with water to form acids under normal conditions. H\u2082 is neutral. N\u2082 and O\u2082 are relatively inert. Oxides of metals, on the other hand, typically form alkaline solutions when dissolved in water (e.g., Na\u2082O + H\u2082O \u2192 2NaOH).
