Boric acid is used as ant/roach killer as boron is quite toxic to them.

Very interesting. Seems more dilute or adulterated than I had suspected:

In addition to naphthalene mothballs, I've also seen p-dichlorobenzene ones. I didn't buy either type, because they both smell awful and I had no use
for either of them. Might get some at some point though (who knows, they might be banned before long).

I was under the impression that the fine particle size gets into their joints and they become disabled. I think diatomaceous earth works the same
way.
Boric acid is pretty mild stuff chemically. It can be used as an eye wash.
The single most important condition for a successful synthesis is good mixing - Nicodem

I've used the naphthalene moth balls for chemistry - I believe it's produced by sublimation. It's very pure. Both types of mothballs are sold
locally for me. I worry that the para may replace the naphthalene type. I should stock up.

p-dichlorobenzene  That name scares me! A benzene-based organochloride, and
it's suspected to be a carcinogen, no wonder they might get banned.
"Appearance and odor: A viscous black liquid with a sulfur odor"
How could 90% sulfuric acid be a viscous black liquid, what are they adding in the other 10%?

Stay out of public restrooms then. (it's

Also quite toxic to humans as well, especially borax. Because borax is metabolised into boric acid in the body, it can easily cause death. Recently in
the news a family of 4 died when they mistook borax for sugar.

Nitric acid and phosphoric acid can both be found in hydroponics stores as pH down.
The purest brands of sulfuric acid are Liquid Fire in home depot, and Rooto drain opener in Ace, but I'm not sure if they have buffers or not.

The liquid fire I saw in ace hardware in 2009 had buffers listed as one of the ingredients

@ Deathunter88: "Recently in the news a family of 4 died "?
quote from wiki, "Borax, sodium tetraborate decahydrate, according to one study, is not acutely toxic.[27] Its LD50 (median lethal dose) score is
tested at 2.66 g/kg in rats,[28] meaning that a significant dose of the chemical is needed to cause severe symptoms or death. The lethal dose is not
necessarily the same for humans."
IF it was the same, I'd be needing to eat ~229g to pass on or become very sick. basically 132.8ml of solid...
I'm not saying it didn't happen, but could I ask where this occurred? kinda wondering how it was consumed? "... 5 to 20 g/kg has produced death in
adult humans...." from wiki for boric acid... ~423g of that on the light side for me, 1,272g on the high side. so this makes me kinda curious
because that was a strictly human number for boric acid...

I've read that heating it to a boil will deactivate the buffers, i'm not sure about that.

I remember many a person mentioning the $2/2oz. packs of NaBr from wallmart, but I recently saw a larger pack from my local ACE, 2 lb for $5.50.
upgrade worth mentioning. sold as a yellow(mustard) algae treatment in swimming pools.( could have possibly been 1lb, can't find the pic I took)

How much work are you talking? There's no elemental lithium in Li-ion batteries, cosidering cost and time, it'd be as practical as isolating lithium
from bipolar meds.
I think 'buffer' is the wrong term here. Strong acids can't even have a buffer, and it'd be sodium bisulfate if sulfuric was weak.

That is what it is called on the bottle. Sure "buffer" is in fact the wrong word but thats what they are called.

Quote from wiki a few lines later:
But this is highly misleading, as humans have been known to die from amounts only a small fraction of the LD50. "The minimal lethal dose of ingested
boron (as boric acid) was reported to be 2–3 g in infants, 5–6 g in children, and 15–20 g in adults", according to the Agency for Toxic
Substances and Disease Registry.

Lithium batteries are a different breed to Li-ion batteries.
Lithium batteries contain lithium foil wrapped in itself using a suitably inert electrolyte, generally dimethyl carbonate.
