What is the role of CO2 in soda water or in any other beverages? While drinking soda water, is there any use of this CO2 to our body?
We used to drink soda water or other beverages, which is prepared by dissolving Carbondioxide having the molecular formula CO2 in water or other solutions at high pressure. What is the role of CO2? To what extent the carbonated drinks are useful to our body?

When CO2 is dissolved in water it combines with a water molecule to form carbonic acid - H2CO3. As long as this drink is under pressure, the CO2 stays dissolved. When the pressure is released, some of the CO2 escapes as fizz, or bubbles. The carbonated water changes the taste of the water, and also gives it that acidic "bite' that you sense when you drink it. Any CO2 that you ingest is either released through burping or some may enter the blood stream where it would be buffered by the other components in the blood.
Carbonated drinks (those containing CO2) have no role in keeping you healthy. Cavemen survived without it. Your body mainly uses CO2 from breathing for regulation of blood pH levels. As mentioned by ndnordic it is vitally important for buffering. This is a chemical process that allows your blood to function optimally.
