Is powdering a carpet with Borax a good way to kill carpet beetles without killing the occupying human?

I've used borax to assassinate the ant queen(s) before.

Mix it 1/3 parts borax, 1/3 part sugar, 1/3 part hot water. Let it cool then let the sugar solution sit out in a flat dish or something. I dunno if beetles are as sensitive to borax, but I'm sure they don't have a processing method for borax.

Borax will kill the bugs but any eggs they leave behind will be spared. You'll have to continuously reapply over months to get rid of all of them.

I'm going to describe a process and ask some questions at the end (though any helpful feedback is good)

  1. heroin dissolved in isopropyl alcohol
  2. baking soda added
  3. caffeine about 1:1 to lower MP
  4. iso evaporated onto foil

The end result way too baking soda and some went into my throat in scalding liquid form. Good thing heroin kills pain.

  • what's that called when two substances are mixed to create a lower boiling point?
  • Is it safe to vape that baking soda?
  • If I used soda ash, would it be safe to vape that too?
  • any recommendations?

Its called freezing point depression. Pretty cool shit, back inna days people determined purity and molecular weight with that effect.

Vaping either baking powder or any inorganic nontoxic base wont be a problem unless you inhale too hard.

Concerning the solvent, just look for the swg drugs heroin dossier( guess thats what your chart is based on?) or someother tables to check which solvent is useable for both the HCl and the freebase. You dont have to add the caffeine while thd h is still is in solution as long as you mix it thoroughly

Id recommend using as little solvent as possible while not slowing the dissolution of the base down too much and installing gentoo just to be safe

Deprotection. Sorry, I was /benz/ed as shit when I decided to legitpost on a few boards. I mean, the information is still good.
Fuck I should teach more when I'm benzed no i really shouldn't

No. You use as little water as possible with an ice bath and then do a vacuum filtration when the freebase precipitates. I don't see why an extraction after freebasing wouldn't work. However, I don't really work with that stuff as much and have no idea if it acts like morphine chemically (it shouldn't due to no active OH groups). Alternatively, You could do the boil down and then acetylate the morphine back into diamorphine.

I'm too chemical, though. I would look up conversion between #3 and #4 or whatever on the internet. Homebaking is much easier than what I would do.

So I used sodium carbonate super-saturated (pH was ~10-11) then added some heroin salt -> tried using hexane to extract it -> evaporated.
Evaporating is always the worst step for me, because unless you're doing a massive batch, you end up with such a small amount of freebase residue, so for max efficiency I try to evaporate directly onto foil, which means I try to make a wide dish out of foil, which often ends up breaking and leaking all over my desk, BUT when it does work Im able to vape right off that foil. The alternative would be to put it solid container, but there's ALWAYS some waste when you try to scrape it all up.

So did it get me high? barely. Not enough. Wasteful.

Si has a lower electronegativity which is one way of explaining that Si- bonds with certain elements behave quite different that C- bonds. Alkanes are quite unrractive whereas silanes react rapidly with water for example.

Another example of sadly untrue hypothesis about xenobiology is arsenic using rna analogues. Sadly arsenic acid esters cant substitute phosphoric acid in neither rna nor energy transport systems because they hydrloyse a looot quicker. I think NASA pushed a study about arsenic using bacteria that cost some poor women her career

The abundance of elements throughout the cosmos is also related to how heavy an element is. Thus its less likely that thered be biologies using elements beyond the second period.
Or rather, even if its possible a lot more biology systems will use second period elements.

The only xenobiology hypothesis that i really like is flourine
Using peptides since theyd behave in a distinct folding pattern eventhough F is almost isosteric to hydrogen. With flourine polymers you could build alot of additional kinds of membranes but flourine is "really" electronegative and with its ole 19 which is just a bad number for being made by stars its unlikely to play a huge role. I could dig out a few papers on that but thatd be off topic

I remember reading somewhere that scientists were able to genetically engineer a bacteria that was able to create silicon bonds, to demonstrate that silicon-based lifeforms are possible and could maybe be found somewhere else in the universe. However I do not believe that they got so far as to create a glucose molecule with silicon instead of carbons. That kind of science is probably decades or centuries away. The reaction you have there is "balanced" in the sense that there are equal numbers of each atom on both sides of the equation. I think your teacher was just trying to tell you that you are full of shit.

The electronegativity. Si forms sissy bonds compared to carbon. It's a harsh universe out there... lots of O2 and water. Without the strength and versitility of the carbon bond, silicon based lifeforms would get wrecked by the simplest forces of nature.

So me and my colleague are arguing about whether KOH or NaOH is stronger base. While in practice it is not important, I'd argue that theoretically it must be KOH, as the enthalpy of K+ is lower, therefore KOH will be more likely to dissociate. However, the colleague is buzzing around with a dubious Pkbn from chembuddy which states that pKbn values for NaOH and KOH are 0.2 and 0.5 respectively, indicating that NaOH would in fact be a stronger base (and LiOH the strongest). Why would that be? Pls explain. pic unrel

Electron density is spread out in potassium compared to sodium. This is why potassium carbonate is slightly soluble in acetone compared to sodium and why you see cesium carbonate used in research papers.
The same holds true for hydroxides.

Any difference between the two is likely very small, but I would have to say that NaOH is stronger because Na is less electronegative than K, so it is more willing to give up that OH group. Pure speculation tho

That logic makes no sense to me; I would expect Potassium to be more likely to give up the ghost due it its relatively large electron cloud. The distance of the periphery of the electron cloud to the center of the atoms nucleus should allow easier access to its valence electrons, no?

Which is why pure cesium reacts so violently in water in comparison to lithium, sodium, and potassium.

I guess what I'm saying is NaOH being stronger than KOH goes against my intuition.

Nvm, I gets it.

The ionic association of potassium is stronger than sodium with anions, so you would expect less dissociation as the alkali metals get heavier.

If E=MC^2, then how is it possible that a mass-less photon can carry any energy?

I expect there's probably a well established answer to this, but in trying to track it down I'm realizing a lot of this stuff is well above my reading level.

sup /chem/,

Looking for some decent DIY battery ideas. Doesn't have to be too compact, but I would like for it to fit on a desk perhaps and be able to shit out roughly 1.5-3.5V and maybe max ~25mA.

I've tried my had at a few types (pic related: quick dirty Earth battery with copper and zinc cathode/anodes) including earth (using several combos of cath/anodes), zinc-air, Al-air, and am setting up to create a MnO2+Alum/graphite cell just to test.

Question: What are some decent DIY battery builds? I'm not asking for any steps, simply just metal combos and whatever medium suites said combo. The charge density isn't all that important as it's to be expected to need to be recharged/reloaded. I'm certain with another cathode/anode in the Earth Battery pictured and a simple joule thief, I could squeeze out around 1.5V (haven't checked the amps yet). The idea here is just to get more ideas for DIY batteries and perhaps ideas for better performance. I'm aware of galvanic series and electrical potential, so I believe this thread is best suited for discussion and possibly personal experience.

Cheers

I recently did some undergraduate research with a professor in organic synthesis and was curious about what the factors for solubility are. I was under the impression that it was all about size and polarity, but i'm getting conflicting results. I had synthesized several molecules which had phenyl groups. Since this was some discovery chemistry, I made "copies" of these molecules but with substitutions at the para positions of the aromatic ring in order to increase reactivity through electron withdrawing effects (para-nitro substitution) or decrease reactivity through electron donating effects (para-methoxy substitution).

What I noticed was that my molecule which had two phenyl rings with para-substituted nitro groups was more polar than the same molecule with no substitution (least polar) and that with the para-methoxy (middle polarity), but it had the worst solubility of the three.

In fact, the one with the unsubstituted aromatic rings was the most soluble in methanol, despite being the least polar.

What factors are at play here? the nitro compound basically only dissolved decently in DCM, which made working with it incredibly frustrating. Yet slightly more or less polar solvents didn't or barely worked to dissolve it. I'd like to know what factors to consider for the next time I work in a lab so I can more easily predict some of the properties of the molecules I'll be synthesizing.

The Nitro-substituted molecules probably have more lattice energy (solute-solute interactions), making it more difficult for the methanol to get in there. Think about how the molecules could potentially crystalize.

If you just have phenyl groups on something else uninteresting, there's not much opportunity. Maybe some pi-stacking. Wheras with the nitro group, you might have some strong H-Bonding going on.

>I'd like to know what factors to consider for the next time I work in a lab so I can more easily predict some of the properties of the molecules I'll be synthesizing.

Most of the time, just go off polarity and like-attracts-like. Then try out different solvents. Unless you're doing QM simulations, this is the best way. And even then, your empirical results will come in faster.

Solubility is a function of associative energy. If you can keep the different types of energies straight, you can think of them as vectors (I think), and if two compounds wind up next to each other on the plot then they're miscible/soluble.

Hansen is newer and more sophisticated than Hildebrand I believe

So if we have all these equations for solubility, how hard is it to throw it all into a program where you draw any molecule and find out what it's soluble in (and how soluble).

It's faster to simply use a rule of thumb, and try 3-6 of the common lab solvents before you find the best solvent (and how soluble it is).

If you really wanted to do it computationally, then you'd need a great graphics card, and a workflow for DFT calculations. There's a handful of programs used for this, and they all have a high learning curve. Spartan is probably the easiest, though it's closed source and expensive. I don't know the exact steps needed.

In general, it's pretty hard.

Actually, Amazon ec2 would be better than a good graphics card. But you'd still want a decent card for when you're leanring.
