\nCarbon dioxide (CO\u2082) dissolves in water to form carbonic acid (H\u2082CO\u2083). Carbonic acid is a weak acid that partially dissociates into hydrogen ions (H\u207a) and bicarbonate ions (HCO\u2083\u207b), thus lowering the pH and making the solution acidic. The reaction is CO\u2082 + H\u2082O \u21cc H\u2082CO\u2083 \u21cc H\u207a + HCO\u2083\u207b.

\n– An acidic solution is formed when a substance dissolves in water and increases the concentration of hydrogen ions (H\u207a) or hydronium ions (H\u2083O\u207a).
\n– Non-metal oxides, like carbon dioxide, often react with water to form acids.
\n– Oxygen, Nitrogen, and Hydrogen are non-polar or weakly polar molecules that dissolve in water but do not react chemically to produce acidic or basic solutions; they remain neutral.
\n<\/section>\n
\nThe acidity of solutions of gases like CO\u2082 is important in various natural processes, such as the formation of acid rain (from oxides of sulfur and nitrogen) and the buffering system in blood involving carbonic acid and bicarbonate. The dissolution of CO\u2082 in oceans leads to ocean acidification.
