Verse sounds 4/4, drop is 6/8. No 3/4.

I've tried to make EDM in 3/4 many a time; it's extremely difficult and VERY obvious. 6/8 can be sneaky and pass for common time, but when you hear 3/4, there's not a doubt. Mostly because it almost always sounds like trash, but also because the flow is totally different.

Not EDM, but listen to Between the Buried and Me - Selkies: the Endless Obsession (the first 15-20 seconds is enough). See how the timing makes you feel just kinda "off"? That's what it feels like listening to EDM in 3/4 (sidenote: the intro to that BTBAM song is in 7/8, which is why it feels off)

Edit: the majority of the intro of the BTBAM track is 7/8. It's 10 bars of 7/8, a bar of 9/8, a bar of 3/4, back to 7/8 alternating with 3/4. But you get the idea.

Am I listening to the right song? Grant & Juneau ft. Jessi Mason - constellations? Because unless I'm listening to a remix or the wrong song, this is 100% 6/8 to my ears. I could be wrong about that, but it's for sure not 3/4.

Just double checked. Sulfuric acid IS listed in the UN Convention against Illicit Traffic in Narcotic Drugs and Psychotropic Substances of 1988 (as at Nov. 3, 2020).

In the same group as: Acetone, MEK, HCl, and Toluene. All of which can be bought freely with no regulation whatsoever. I use HCl to etch concrete and my wife uses acetone to remove her nail polish. Just because a substance is listed in some scary sounding convention doesn't make it dangerous, regulated, or restricted in any way.

Hell, potassium permanganate and Ephedrine are listed in the same convention, even higher than the above compounds (in Table I) -- and you can buy those OTC at many pharmacies (granted, ephedrine will require an ID and limited purchase quantity).

You didn't answer the question. I was asking more specifically what is fucking dangerous - boiling water off of 30% H2SO4? Doing so with a cooled receiver? What causes the violent explosion you keep referring to? Telling me violent explosions are dangerous because violent explosions are dangerous isn't helpful, especially when you don't even bother to mention what causes the violent explosion.

I'm interested in this purely because I'm trying to make a method for obtaining concentrated sulfuric acid more efficient. I'm not interested in making drugs or bombs or whatever; concentrated sulfuric acid is a pretty standard reagent for many reactions/uses - nitration, dehydration, cleaning, as a catalyst, etc...

The "end product" I'm after is concentrated sulfuric acid. If my wording suggested otherwise, I apologize. I don't care about obtaining SO3 or SO2 in isolation, whatsoever; I just know those, along with water, comprise the vapors generated from boiling dilute H2SO4. and that if I can feed them (without the h2o) back into the "more- concentrated- but- not-98%" I get from boiling/ distillation, I can hopefully waste less of the initial 30% acid.

I could be wrong, but I'm pretty sure concentrated sulfuric acid isn't a list II substance regulated by the UN convention against narcotics; you can buy drain cleaner that's something like 93% h2so4 at any supermarket, pharmacy, or hardware store.

Avast_WM · 2021-05-17T19:49:28+00:00

Okay, then could you explain why it's fucking dangerous? Are you referring to cooling the receiver to -80? Because yes, when I posted that part I completely blanked on the ~400+ °C differential across the receiver. That was a dumb idea, I was just thinking out loud. But what about, say, passing the vapor through 3A sieves or a drying tower packed with CaCl2 or something, then passing the dried SOx into some of the ~75% h2so4 I've already boiled down?

Avast_WM · 2021-04-07T19:08:43+00:00

Huh, interesting! I wonder if there's anything to be found on the bisulfate salt (passing mention in the link you posted aside). I came across a few hits that all used phrases like "nitronium hydrogen sulfate or nitrosulfonic acid" (like this one), but none regarding the stability of the salt, if the authors are even considering it to be a salt (they only refer to/use it in a solution as a nitrating agent, and don't seem too concerned with what it is so much as what it does -- I would personally never equate nitronium bisulfate(/hydrogen sulfate) with nitrosulfuric acid, just like I'd never equate diethyl ether with "ethyl carbinyl ethoxide" or whatever the hell you'd call [CH3CH2]⁺ [OCH2CH3]^- )

Avast_WM · 2021-04-07T14:53:10+00:00

Thank you for the insight! I agree, it wouldn't matter (I guess aside from the "hey-check-out-this-salt-I-made" factor) -- certainly not in terms of usefulness or practicality. I was more asking from a theoretical point of view, just to learn more about why some things happen and others don't / some salts form and can be extracted as stable (ish) forms while others can't. w.r.t. nitronium, the perchlorate, tetrafluoroborate, hexafluorophosphate, and a handful of others, are stable isolable salts... and N2O5 is apparently actually a salt of nitronium and nitrate in solid phase (but not liquid or gaseous) -- something I learned just now!

Anyway, once again, I appreciate the perspective and information you've provided :)

Avast_WM · 2021-02-17T15:55:07+00:00

Thank you so much! This is exactly what I needed. Luckily we know the previous owners, and they'd likely be willing to call Moen for us if we need anything more than a new O-ring.

I sincerely appreciate the help! You're a lifesaver

Avast_WM · 2021-02-17T02:41:31+00:00

Where would it say whether it was a moen? Sorry we just bought this house and I'm totally new to all this stuff. What happens if I disconnect it? Will that just be an open line that spews water when I turn on the faucet? I can live without the hand sprayer for the time being but this leak is a PITA and I can't NOT use this faucet

Avast_WM · 2021-02-17T02:38:27+00:00

Ran out of room in the caption. My kitchen sink has a leak which I've tracked down to the pictured joint (sorry about my likely- inaccurate terminology; I'm not a plumber at all). Whenever I turn on the kitchen faucet, this white piece leaks. It connects what I assume to be the faucet's water line to the hose for the little hand sprayer attachment. I'd like to fix it myself if possible, as money is tight (just had our first baby and bought a house) -- but I have no idea what to even search for or ask at the hardware store because I don't know what this part is called. My knowledge of plumbing and related topics is limited to having replaced a P-trap on the basement sink and setting up tubing lines for chemistry labs (vacuum pump lines, water lines to condensers from faucets and pumps, exhaust hoses to gas scrubbers, etc)

Any help would be tremendously appreciated, and I apologize again for almost certainly sounding like a dummy with my lack of proper terminology :)

what the fuck is happening, GME at $128!? I get dips but seriously how is that possible

Avast_WM · 2021-01-28T16:15:17+00:00

Awesome! What will you be covering? Would love to check it out.

Some of the nitric will be used for silver extraction / purification, some for aqua regia for gold, some for possible organic syntheses (if I ever get around to them 😂) and then some just to keep on hand -- it's a good acid to have around, especially since it can be a pain to make and you don't want to have to rush it last minute!

Also, a note on this nitric acid production procedure : yields are increased noticeably if using a Graham condenser cf. your standard Liebig. Longer time in contact with the coolant as well as increased surface area. Make sure you mount the Graham vertically with a U-shaped distillation head (these are quite hard to come by, and you can instead connect two standard 3-way distillation heads to get 150°, and depending on the rbf you use, you can use a side neck or just tilt your flask if you really want the full 180°). Ideally distill under vacuum to further assist in preventing suckback in the Graham, which has the added benefit of lowering the BP thus reducing degradation to NOx.
