Portion of CO2 in the air can disappear when it is bubbled through an aqueous saturated solution of calcium hydroxide Ca(OH)2 commonly called limewater.
A cold product of this chemical reaction is calcite crystal, one of the most common minerals. As crystal of Iceland spar, it has the property of double refraction. As translucent or opaque rock, it becomes the beauty of marble slabs. A hot product is aragonite rock, a less stable form of calcium carbonate, CaCO3. Aragonite usually occurs as a deposit in limestone caverns, or as a precipitate around hot springs and geysers, or in highly pressurized low-temperature metamorphic rocks. It forms the outer skeletal structures of mollusk and coral and is the only substance for pearls. Pure forms appear white or colorless. Impurity creates varieties of tints: grey, blue, green, or pink.
Where and when it is possible to engineer lime rain instead of acid rain then atmospheric CO2 will be drastically diminished.
Time independence: [∂E(g)]²=[∂F(a)×∂r(a)]·[∂F(b)×∂r(b)] and Mass independence: ¶a(t)·¶r(t)=c²
