How to dissolve Carbon Dioxide into Water

I am interested in finding out how this is done on an industrial level.
I understand that dissolving CO2 into water produces carbonic acid.

If u apply enough pressure than you can desolve it in water.
But to keep it desolved you have to maintain pressure otherwise it will go away like when we open a soda bottle the bubbles of CO2 detaches from solution.

You are correct about carbonic acid.
Probably the thing to know is that you can dissolve more CO2 in the water under higher pressure.
The opposite happens when you open a container of soda water -- the pressure is released and some of the carbonic acid dissociates, producing bubbles of CO2 gas.

The process of adding CO2 to water is called "carbonation". Putting that word in any search engine ought to find you details.

Hope you like my anwser:Carbon dioxide (chemical formula CO2) is a naturally occurring chemical compound composed of two oxygen atoms covalently bonded to a single carbon atom. It is a gas at standard temperature and pressure and exists in Earth's atmosphere in this state, as a trace gas at a concentration of 0.039% by volume.

As part of the carbon cycle known as photosynthesis, plants, algae, and cyanobacteria absorb carbon dioxide, light, and water to produce carbohydrate energy for themselves and oxygen as a waste product.[1] But in darkness photosynthesis cannot occur, and during the resultant respiration small amounts of carbon dioxide are produced.[2] Carbon dioxide also is a by-product of combustion; is emitted from volcanoes, hot springs, and geysers; and is freed from carbonate rocks by dissolution.

As of July 2011[update], carbon dioxide in the Earth's atmosphere is at a concentration of 392 ppm by volume.[3] Atmospheric concentrations of carbon dioxide fluctuate slightly with the change of the seasons, driven primarily by seasonal plant growth in the Northern Hemisphere. Concentrations of carbon dioxide fall during the northern spring and summer as plants consume the gas, and rise during the northern autumn and winter as plants go dormant, die and decay. Taking all this into account, the concentration of CO2 grew by about 2 ppm in 2009.[4] Carbon dioxide is a greenhouse gas as it transmits visible light but absorbs strongly in the infrared and near-infrared, before slowly re-emitting the infrared at the same wavelength as what was absorbed.
