Influence of Lack of CO2 on Anaerobic Bacteria: a Quick Method To Verify the Absence of CO2

Since CO2 is carbonic acid gas, it will decrease the pH if added to water. Therefore, a simple test can determine whether CO2 is present in a gas mixture. If the pH of gassed water does not change significantly, then CO2 is not present in the gas.
