    As part of a school science project, I have to prove the effects of excess carbon-dioxide on the human bloodstream.

    However, being high school students, we are not allowed to use actual blood.

    I was hoping someone could tell me how I could use an experiment to prove this.

    My teacher hinted that it would be possible using the pH of water, but I have no idea what she meant, or how to do it.

    Thus, I need your help. Much appreciated.

    The only thing that I can think of, is:

    1) Test the Ph value of water.

    Now........Buy yourself a soda stream fizzy drinks maker.......

    But water in the bottle and stick it in the device and press the button on the canister a couple of times.

    Take the bottle out and now test the Ph value of the "fizzy water"

    If you dont have access to a soda stream then buy two bottles of mineral / spring water. One still and the other sparkling and test the Ph value of both.

    The gas which is used to make drinks "fizzy" is CO2 (carbon dioxide) and it turns water into something which can be called "Carbonic Aicd"

    Hope this helps ?

    Could work^

    However, I searched a little and found that if I took the pH of water every so often when blowing into distilled water with a straw could give results.

    What do you think?

    Yes that could work; although you'd also be blowing in unused oxygen, nitrogen and small amounts of trace gases.
