mScientist Posted January 21, 2012 Share Posted January 21, 2012 How can I know what kind of gas I have in a closed jar? Is there any experiments I can do to know what kind of gas I have? thanks. Link to comment Share on other sites More sharing options...
Suxamethonium Posted February 8, 2012 Share Posted February 8, 2012 lol... there are lots of tests- some more affordable than others. Colour, smell, and density are all fairly easily determined. As is pH. You could test for oxidising properties (O2, Cl2, N2O for example) or flammability (H2 or HCs for example- if so, run an ms on it). You could measure its UvVis absorbance to compare curves with known (suspected) compounds. Various gas tests like CO2/limewater tests could be imployed. Depending on what the application is, its only likely to be a select few gases- it shouldn't be too hard to deduce it from logic and trivial data alone.
