Will my SN still work after opened?

[ancryxia]

I left my SN out and exposed to air. About a week or two ago I decided to CTB, got the SN out, mesaured it, but then decided not to. It was left out for maybe 10 minutes at the most. Will it still work? I heard it turns to nitrate with air exposure. It is 99.6% purity. I want to CTB tonight finally.

Also, I'm aware I've already posted this before. I'm reposting in hopes to get more answers

I wouldn't think it would turn to nitrate that quickly, but I'm no expert.

I don't think it can lose potency just in 10 minutes. Maybe dose 20g instead of 15g just to be sure?

So you opened the bottle, measured your amount, and left the bottle open for 10 minutes? Is that correct?
You may as well throw the first weighed amount out,
As for the bottle, I'm sure 10 minutes is nothing, I mean someone using it for normal use probably has it open for that long.
Even if the stuff at the top of the bottle has turned, i reckon the bottom stuff will lstill be good if your that concerned.
