Thanks. Garcia Oliver. Plants absorb CO 2, of course, but they take up a lot of room and are slow, inefficient CO 2 absorbers. 2 scrubbers use chemicals that don't meet your criteria. Monoethanolamine (MEA) is used to scrub carbon dioxide from gas streams, but it's corrosive and toxic in very small amounts.hanks. Garcia Oliver.

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.
