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.
1 About Titanium Dioxide What is titanium dioxide? ï· Titanium dioxide (TiO 2) is a white solid inorganic substance that is thermally stable, non-flammable, poorly soluble, and not classified as hazardous according to the United Nationsâ (UN) Globally Harmonized System of Classification and Labeling of Chemicals (GHS). Based on existing safety information, it can be concluded that the use of titanium dioxide nanomaterial (ultrafine) as an ingredient in cosmetic sunscreen products at a concentration up to 25 % poses no risks to human health (12, 13).
