How do I measure the SN?? Stupid question...

[Hope:-)]

People have told me that it's better to add the SN after you pour 50ml of water. To do it this way, do you get a different glass, measure 25 grams of SN into it and then pour the SN into a 50 ml measure amount of water? I know this sounds dumb but I find stuff like this hard to work out. Is it ok to do it my way- that is get the glass I'm going to drink from, measure 25 grams of sn into it and then slowly add the 50ml of water to it and thoroughly stir. If anyone could let me know it'd be much appreciated.X

Do standard baking like measuring cups not have the right measurements we need ? That's what I've always imagined using. I'm interested in finding out as well

No this is not a stupid question !! You never know until you ask

(Maybe this was a stupid reply after re-reading, whoops. Think I wasn't understanding right)

Personally I plan to do with an electronic kitchen scale, it works very well with kitchen salt. Afterwards, I think that measuring the SN and adding the water to it directly in the same glass should not be a problem. This should even avoid losing a few grains of SN.

Water first can be better because the area of SN touching water will be greater - if it's already there then it can dissolve slower.
while we're on a subject, does anyone know how much is 25g in tablespoons? i don't have a scale...
also you don't need to use a different glass, just weigh the water glass and add SN to it. You could also weigh the SN container and take 25g from it

I have finely granulated sodium nitrite and I will be using 1.4 tablespoons which is around 20ml in one of those caps that come off of a cough syrup bottle.

That's how I would do it.

If you can make sure everything is dissolved, I think how exactly you got there shouldn't matter. Info from Wikipedia seems to suggest you could dissolve 42.4 g of SN in 50 mL of water (at 25 deg C). The popular guide says this amount of water is used to make it more palatable but it still brings up the possibility that not everything will dissolve, not sure why.

I have finely granulated sodium nitrite and I will be using 1.4 tablespoons which is around 20ml in one of those caps that come off of a cough syrup bottle.

For those who can't get a granular enough measuring cup, you could just make a box out of card or paper or something that's the exact volume e.g. 3 cm * 3.5 cm * 2 cm box = 21 mL, saves you having to figure out how to get to 0.4 tablespoons or having to round to a certain container...

Ok this took me down a rabbit hole. I was wondering how people settled on a volume. There's a huge variation in the density of SN quoted on this forum. Some quote 1 tablespoon = 15 g which I hope isn't just because they think 15 mL = 15 g for everything, some quote a nominal value of 2.168 g/cm^3 (implies 1 tablespoon = 32.52 g) you'd find on, say, Wikipedia which I think would be if it was a single crystal.

This thread seems to be the source of an often-shared table. It uses 1 tablespoon = 18.5 g as an assumption.

Here is a post where someone actually weighed out 1 tablespoon at 16 g. Not suggesting that makes it the right value, their conditions might be fundamentally different to someone else's.

If you assumed 1 tablespoon = 18.5 g and it was actually 16 g then with 1.4 tablespoon you'd be short 2.6 g. Is that enough to matter? No idea. Worth noting that the popular guide claims an effective dose of 100 mg/kg body weight so the lower recommendation of 20 g will still be an overshoot for a lot of people.

Thanks. I'm drinking two glasses. I don't think it will make much of a difference regardless.
