After I open my SN bag how long will the SN last before it loses it's effects
wow it looks like it's fastGoogle it! I think it starts turning into nitrate pretty fast.
Days? Oxidation does not take days to happen, it's a very slow process otherwise once it's opened, why should anyone using sn for analytical purposes even need to use it if the oxidation process renders the Nitrite useless in days.I think it lasts until its expiration date if sealed back up, but I'm not sure. Could be that it only lasts a few days.
wow it looks like it's fast
even if I keep the bag sealed?
No, it doesn't start to oxidize until it's in contact with air. Also try to keep it away from sunlight and humidity! AND take a test to check it's purity. Hope this helps a bitwow it looks like it's fast

Well, this is what matters for anyone to know.The fact that it's a slower process suggests that sodium nitrite doesn't rapidly decompose when exposed to air but rather diminishes gradually.
Does this happen when it's exposed to air even just after opening it once or is it frequently because usually SN is used in labs primarily to this may be aimed at that. If the degradation varies per environmental factors such as heat sources, reactant material or moisture then that 82.3 day time limit may be limited to how the SN is kept and in what prevailing conditions.The term "half-life of 82.3 days" indicates the time required for half of the sodium nitrite to degrade.

So if half of it degrades inside 82.3 days, how long until it's practically not able to be used.In simpler terms, sodium nitrite doesn't rapidly disappear but slowly diminishes over time due to these chemical reactions.
