Carbon dioxide as a non-metallic oxide is acidic. Carbon dioxide reacts with water in a reversible reaction to form carbonic acid (H 2 CO 3). CO 2 (g) + H 2 O (l) H 2 CO 3 (aq). The acid dissociation constant for carbonic acid K a = 4.45 x 10 -7 mol dm -3.arbon dioxide is a simple covalent molecule that most people have heard about, as it is often in the news linked to global warming. Carbon dioxide has the formula CO 2 and at the centre of this linear molecule is a carbon atom joined by two pairs of double-bonds to the oxygen atoms, i.e O=C=O.
This naturally occurring chemical compound is made up of a carbon atom covalently double bonded to two oxygen atoms. Carbon dioxide exists in Earth's atmosphere as a trace gas at a concentration of about 0.04 percent (400 ppm) by volume. Natural sources include volcanoes, hot springs and geysers, and it is freed from carbonate rocks by dissolution in water and acids.
