WebHow are soft drinks carbonated and what is the pH of soft drinks? Carbonation is a process wherein pressurized CO 2 is passed through water, producing carbonic acid along with dissolved CO 2 gas. Most carbonated drinks, which are approximately 94% water, have pH around 2.5 to 3.5, and hence are highly acidic. WebThe typical soft drink is carbonated at 2.5 atmospheric units (atm), resulting in a high concentration of dissolved CO 2 and an acidic medium of pH 3.7. At normal atmospheric conditions, dissolved CO 2 is low and soft drink pH is now closer to neutral (around 5.7). The amount of carbon dioxide pressure also depends on the type of soft drink.
