Help SN air exposure

[ifckinhatelife]

How long can I leave sodium nitrite exposed to the air before it reduces its effectiveness?
I was planning on keeping it on the table, ready to mix, several hours before drinking.

If you mix the SN in water in an entirely plastic container (the cap should be plastic too), it should be OK for a week.

Thanks. But what if it's unmixed and not tightly covered or sealed?
I want to seperate the correct amount from my SN bottle first, so when I'm ready I can mix it with water immediately.

Or is it safer to mix it with water and seal it in a bottle?

It's safer IMO to mix it in a bottle and tightly seal it and keep the bottle for no more than a week in a dark place.

Thank you. That was helpful.
