It partially ionises to form hydrogen ions. H 2 CO 3 H + + HCO 3 -. The hydrogen ions from carbonic acid give natural rain water a slightly acid pH value of 5.6.
It is true that increased carbon dioxide concentration in the atmosphere would be expected to increase the greenhouse effect and possibly cause warming. It is unclear whether global warming is due to increased carbon dioxide concentration or if carbon dioxide concentration is the result of global warming.t is unclear whether global warming is due to increased carbon dioxide concentration or if carbon dioxide concentration is the result of global warming.
