Dissolved carbon dioxide (CO2) is naturally present as a result of animal respiration, the decay of organic matter, and the decomposition of certain minerals. It is the major source of acidity in unpolluted water samples. Surface waters typically contain less than 10 ppm (mg/L) dissolved CO2, while ground waters, particularly if deep, may contain several hundred ppm (mg/L).
CHEMetrics’ carbon dioxide test kits employ a sodium hydroxide titrant and phenolphthalein indicator. The kits contain a neutralizer solution to correct for sulfide interference. Results are expressed as ppm (mg/L) CO2.
If no shelf-life is listed for a product, then the shelf-life is at least 2 years. |
