I planned to ctb on Saturday so I weighed out some SN and placed in a ziplock because I planned to CTB away from home. Once I reached my destination however I simply couldn't bring myself to do it, partly due to SI/guilt but mostly due to thinking I didn't have enough time/not sure if I was hidden enough to not be found in time to be "saved". I transferred it back into the original bottle but now I'm afraid its not pure. So the question is- how quickly does sn become nitrate? And can it be stored in ziplock bags (tried to get most of air out but some remained)? Thanks.
