Title: [CO2] experiment
Post by: santibravo on September 27, 2014, 04:14:28 PM

Hey guys, I need a little help to complete an experiment.
I need to calculate the CO2 concentration of a determined quantity of air. I know that if I got a closed system and purge the gas into Ba(OH)2 (aq), it will precipitate. Nevertheless, I have been searching methods to purge gases and have not been successful(english is not my native language). Can somebody explain me how can I do this experimentally?
Thanks!
