Resource Stability of SN and N

[cme-dme]

But would the vacuum sealed bag be enough or would it go bad if it's not put in a second container? I assume it's probably stored like that for a long time anyway and ships that way so probably but does anyone know in more detail

I think its fine as long as it remains in the sealed bag.

Nitrate does not produce nitrogen dioxide in reaction with these acids. Commercially available curing salt can be used as a comparison, it will have a reaction, but it is not going to be significant. Sodium nitrite is an important chemical, there will always be a demand for it. Some crazy kids on YT are experimenting with it, and these videos can be used as a reference.

So you need the reagent not the commercially available version? Will the commercially available still work? Not the obviously unpure ones that actively state 10%. I guess I just need to know the purity of it, but obviously the reagent would be better, if more difficult to find.

I assumed mine was 99%, because that's what I searched for. Went through significant barriers to even get that. But, it's sounding like the commercially available sort is a mixture of various compounds, whereas the reagent is pure.

I'm guessing if it comes in a plastic bag in multiple KGs it's probably not pure, huh.

What about melting point tests? Any issues with those? Should be 271C melting point for sn. Simply using a capillary tube, heat source/Bunsen burner, and a thermometer. Wouldn't be able to determine total purity, but if it melts at 271C should be relatively pure.

I assume the purity is good to go ?

Onto Nembutal, although it isn't talked about much anymore

I haven't been here in a while. I thought N was the default? Has something changed since? Not that I'd have access to it anyway...

I have a question: I got my SN in a black plastic screw cap bottle (im not sure if it is HDPE or PP), it came sealed, but I broke the screw cap seal to open it (i did it only once) to check it out, screw it back, and now the plastic bottle is inside a box in my drawer.
It seems well closed like a normal bottle would be. I opened and closed it over a month ago.
It was manufactured in 2024 and the expiration date says 2030. I don't intend to CTB soon, for now i'm just perfecting the plan,so I'm thinking of keeping it until it expires. But reading this and other threads I got quite confused...
Can the air particles that the closed SN bottle is exposed to be enough to diminish it's shelf life to, let's say, 1 year, or some months instead of 6 as stated by the manufacturer? As I said the closed bottle was opened a month ago, I'm not sure if I diminished its potency (I couldnt find aquarium test strips to test its purity where I live, I really tried) to the extent it became unusable.
Also, there's a considerable gap between the salt and the cap, like just a tad more than the half of it.
If so, should I order another SN batch and just trust the same manufacturer and never check it this time around and put the sealed bottle in a kitchen airtight jar?
I've read that I should put the SN in an airtight container, or that I should keep it in its original bottle, some sources claimed that it couldn't be a "normal airtight kitchen jar"...
I'm afraid of asking these questions to the manufacturer and raise suspicions...

Thanks!

can we mix the solution a few hours in advance?

If you mean the small clear glass bottle with a black cap, these are for display. But relocating the NaNO2 into a glass container is a step in the right direction. This chemical almost always ships in a plastic container or even in a plastic bag. According to research done for the U.S. Department of Homeland Security, around 525 micrograms of water diffuses through HDPE each year.
NaNO2 in a solution should be stored in a refrigerator.

Is there a difference if it's stored in neutral or alkaline glass? I just know it's got to be amber colored

Could someone please private message me where I can buy sodium nitrate in the UK. Thank You
