dissolving CO2 in water....
« on: September 28, 2006, 05:31:44 PM »
Hi! I'm not sure how to proceed for this question:

Calculate the amount of carbon dioxide dissolved in one litre of water if a pressure of 2.4 atm of CO2 to carbonate the water is used.

Which gas law should I use? Should I use CO2 solubility? ...  My goal is to find out the CO2 concentration after carbonating.

Thanks so much!!

Thanks for your time.. so do I use the pressure used to carbonate the water as pCO2 in this formula?

pCO2 = KCO2 xCO2

Also, if the procedure is done at 0C/273K, for example, then I can't use the usual KCO2 of 29.4 L atm/mol...? I can't seem to be able to find the K for 0C

I'm sorry for silly questions, perhaps...  :-[
