Influence of lack of CO2 on anaerobic bacteria: a quick method to verify the absence of CO2.
Since CO(2) is carbonic acid gas, it will decrease the pH if added to water. Therefore, a simple test can determine whether CO(2) is present in a gas mixture. If the pH of gassed water does not change significantly, then CO(2) is not present in the gas.
