Is it possible to reduce co2 % by using lime stone water to make co2 dilute and formed co3?
CO2 in the air is part of the balance with calcite (limestone) in water. Where that balance is (how much CO2 in the air would be in balance with water in equilibrium with calcite) is primarily a function of acidity of the water (pH). This is really what happens on earth naturally over time, the CO2 content of the air is controlled by the formation or dissolution of calcite from sea water. Sea water (or any water really) can take up a certain amount of CO2, but in doing so acidifies the water (CO2 plus water forms carbonic acid, a weak acid). Normally, the acid is then buffered by the disolution of calcite (which is a base salt). The system normally fairly rapidly reaches the point where it is filled up with disolved CO2 so will not take any more from the air until some of the dissolved CO2 is taken out by forming calcite. In nature, this is how CO2 content of the air is controlled by the amount of CO2 the water can hold, which is a much larger amount than the air can hold. Calcite is p
