Hi everyone. I have been presented with a problem- to produce a set amount of pure, dry oxygen in any way I can, provided it is safe and accessible. I have chosen to tackle the problem by heating silver oxide until the silver and oxygen separate, however there remains the problem of isolating the gas, drying it and collecting it. I was going to displace the gas with distilled water and then somehow get the gas to go through a condensing tube filled with drierite to remove the water vapour (quick note: all this is done in vacuum sealed glassware) so I can collect it. However, gas is a bum to work with, because it wants to fill its entire container. I'm working with high school laboratory equipment, so I unfortunately can't supercool my oxygen. I was wondering if anyone here had any ideas. Also, if anyone sees anything wrong with my partial solution, please tell me before I embarrass myself and my chem teacher. Kind regards, Cat.
