Only 1.45 grams of carbon dioxide dissolve in 1000 grams of water at
20 degrees Celsius (68 degrees Fahrenheit) and one atmosphere of pressure forming carbonic acid, H2CO3, an unstable substance. Ions, shock, heat, or sunlight cause H2CO3 molecules to break apart and carbon dioxide leaves the solution violently.
Carbonated soft drink and wine bottles, which have higher pressures, have exploded in hand
with serious injuries resulting as the small space in the neck of the bottle
traps all the gas produced. Pressure in the neck space rises
to a point greater than the strength of the glass and it fails catastrophically.
Carbon dioxide injected into wet earth dissolves into soil
moisture easily because the soil is still, cold, dark and under pressure. Soil water pressure rises just over one pound
per square inch for every foot of soil depth. Thus, carbon dioxide is increasingly soluble in soil
more deeply is it injected.
At one atmosphere 1.45 grams of CO2 dissolve in one liter (1,000g) of water which sounds like very little, but it is 2952 times as much CO2 per unit volume as air.
Carbonated
water is absorbed readily by plant roots.
It will stay at rest until found by plant roots. A more perfect
container, storage and delivery system could not be made for carbon dioxide. This is
the key to Sequestered Carbon Amendment and Fertilization, the SCAF, system.
