SN testing (need advice)

[unluckysadness]

So I've tested my SN. Can anyone tell me if it seems good ?

Here is what I've used for the first test (stripes on the left (on the floor) :
- 500ml demineralized water
- 2,5g SN

And for for the stripes at the right, I've used
- 500ml
- 3 drops taken from the first bottle

The stripes on the left are darker purple coloured than on the aquarium strips bottle. So do you think my SN is pure enough ? I know nothing about chemistry. And I didn't have distilled water and a pipette that can measure 10 mg so what I made is probably wrong but I wanted to make a first test. I also fear for the stability of the product as I opened it for 30 minutes and it seems that the air leakage is not good

Thanks

Hi, unluckysadness...

I'm not really an expert on these tests either, so I can't help you there.

But I did see someone in a post say that these tests are garbage, claiming they either don't work or just show nonsense. I'm a bit skeptical, since it's possible he was just doing the test wrong. However, as an alternative, he suggested checking the SN with blood.

That alternative sounds... logical, but, uh, where am I even supposed to get the blood from?

The idea of having to hurt myself for this, to put it mildly, doesn't sit well with me. And I haven't had any accidental injuries (like cuts or a nosebleed) in a long time.

It has skull and crossbones logo, so it should be lethal, but I think I'll try to order another bottle. I didn't ask for purity when I ordered mine in april. Now it's too late, and the company doesn't sell it anymore (you now need to have a VAIT number). Very complicated...

Yes, it's logical. The label on my packaging and bottle had all these symbols too (I had to remove them to avoid attracting attention), and so did the datasheet provided by the seller. The seller is reliable as well. But that still doesn't make me 100% confident about what's actually inside the bottle, and given that you ran a test, it seems it didn't make you fully confident either...

I've just ordered another SN from another polish company, and they asked me why I need it (they may cancel it if my answer is wrong). So I've told them it was to test it to fade my jeans, but I guess they won't believe it and they'll cancel it. They say it's 99% pure but I'll let you know.

Good day. I noticed that both of your labels have the same CAS (Chemical Abstracts Service)7632-00-0.
This made me curious as to whether the it meant that the composition the product corresponded to that CAS number.

When you do an internet search on the CAS number you receive the attached detailed screenshot. Which lead me to ask the question above.

Response: "No, a CAS number does not mean that every product with that number has the exact same composition. While the number uniquely identifies a specific chemical substance, it does not account for differences in concentration, manufacturing processes, or impurities that can exist between different products."

This is ironically the same CAS number that is on the SN product from SD in the US which also has no purity stated which I am trying to decide about ordering.

I feel stupid trying to interpret all this as the desperation does not make for good logical deductions. It is all so frustrating.
Best to you both :-)

Many thanks for your post. I didn't know that. Very informative Well, if things are too complicated with this SN shit, I'll consider buy a rope and do partial hanging. Fuck fuck fuck I'm so bored !! SaSu is becoming a chemistry forum. WTF !!

OP - You're welcome! It's like the more you read and try to make assumptions based on information that is not always right or always clear the more rabbit holes you go down.

I wanted to post my process to see if we can get some feedback from people more schooled in chemistry than I am.

I am also trying to figure out whether to buy the SN I am looking at from SD in US as it has that same number which might not mean anything. I had originally tried to buy from German website which they charged my card after I documented reason but shipment has not moved.

Hanging = I was overcome by SI after reading all the Evelyn Lane tutorials and trying both partial and full suspension.
I wish everyone the best. I am going back to the SN search.

May I say I have enjoyed reading your posts - you seem to be very kind. :-)

Which company are you ordering from? Are you buying it on Allegro?

Hi. Yes, the CAS will be the same. You need to clarify the purity with the seller by requesting the quality certificate if it's not stated otherwise (or if you want to get more details on the composition).

I don't know how it is in the US or the EU, but in Russia, they specify the ГОСТ, which (at least on paper) guarantees a certain purity.

For example, according to "ГОСТ 4197-74" (for reagents), there is "Чистый" (Pure) - 98.5%, as well as "Чистый для анализа" (Pure for analysis) and "Химически чистый" (Chemically pure) - 99.0% (the difference is in the regulated limits of other substances).

And according to "ГОСТ 19906-74" (technical grade), there is "Высший сорт" (Highest grade) - 99.0%, "Первый сорт" (First grade) - 98.5%, and "Второй сорт" (Second grade) - 97.0%. The technical grade isn't tested as thoroughly as the SN for reagents; its analysis typically only lists NaNO2, NaNO3, and NaCl.

For instance, my SN is "Чистый" (Pure), but according to its certificate, the purity is 99.25%.

I haven't seen anyone on this forum recommend getting the purest grades, so just consider this informational.

P.S. Just to be clear, I'm not a chemist or anything like that, just studying the information.

P.P.S. Since I'm using a translator, the terms I use might vary from message to message.

@Surek02. Thank you for the response-I appreciate the additional information. Since the internet stated that the same CAS number did not mean that every product had the same composition, what you are saying about the CoA makes sense.

My issue is the source that I am looking at (US based) does not offer anything beyond the handling restrictions and since I originally tried to source from Germany but that shipment has not arrived despite payment and a statement of proposed use.

So, I am trying to figure out another option.

Also the translator appears to be working well. :--)

Hmm. I suppose the question from the screenshot can be used to formulate what might be a "right" answer...
And I think I'll stop posting anything else in this thread. This is making me feel uneasy. Sorry.
