Where can i get a 10 GPH pump. Ive spent like an hour trying to find one. Thanks.
P.S. My hose is to big to attach.

Does your hose have a thread connector? If so, pop on down to the hardware store and get a brass nipple for the rubber tubing with an appropriate
connection to the female end of a hose connector. Cost ~$7, works beautifully.

No idea why I humored you spoon-feeding request....
Could you not type in Google: solubility of potassium sulfate in methanol?
Anyway, this is pretty good.
This isn't as good.

This isn't really a chemistry question...
I have a Nd:YVO4 green laser pointer. Neodymium normally emits in the IR range, but a frequency doubler (potassium titanyl phosphate) is
used to convert it to green light. If I look through the frequency doubler crystal, will I be able to see the world in infrared? Is there any way to
do this with frequency doubling?

Sorry Brain & Force I don't have an answer for you. Anyway...
There is so much ambiguity the solubility of methylamine.
Ive tried to search this one simple question for months
It says right here that methylamine is insoluble in acetone and ethyl acetate? Is this true?
Does anyone know if methylamine is soluble acetone? Are the di and tri methylamines soluble in acetone?
P.S. a bit below it also says MeNH2.HCl is insoluble in most organic solvents. Is this true?

Sea Salt
I have lots of sea salt in my house, we usually use it instead of pure NaCl to flavor our food.
My question is, is sea salt really evaporated salt water, or do they do anything to remove some of the other salts?
Sea water contains decent amounts of Br- ions.
and by bubbling chlorine through sea water elemental bromine is isolated industrially. I don't live near an ocean, but making a saturated solution of
sea salt, and bubbling chlorine, I could make some bromine if it really is evaporated salt water.
2 Br- + Cl2 → Br2 + 2 Cl-.
[EDIT] I guess the only way to test is to just try it. Luckily that will be quite easy. Has anyone else tried this? I suppose iodine could be made the
same way, and it will be produced first, as it can be reduced by chlorine and bromine.... Separation should be easy.

I think that it would be a lot simpler and easier to buy a bromide salt, or pool brominating tablets? What concentration of bromide do you expect from
sea salt? I read 0.2%!

I already bought 100 grams of KBr, but it wasn't very cheap.... Yeah it's definitely easier, but this is how it's done industrially, and I want to
make larger quantity's of bromine.

Sodium bromide is cheap in bulk. 25 kg for 120 pounds: http://www.ebay.co.uk/sch/i.html?_trksid=p2050601.m570.l1313...
Perhaps you have bought photographic grade? By all means give it a try with sea salt, but I gather that it is only economical if you have a whole
ocean of sea water as your starting material.
Good luck anyway.

Search on YouTube for a video by ChemStudy on bromine. It's a very old video but it has a part where they demonstrate lab scale bromine production
from sea water, yields are poor but the video is fantastic, as with all the chemstudy episodes!

Oh, thanks for the link, I don't have 120 pounds ($199.07) but maybe soon. I think what I bought was for spa's but I'd have to check again.
If I do indeed try on a larger scale I will certainly just buy NaBr or KBr bulk, rather than sea salt...
I still would like to try and see if sea salt does contain bromides.

I will thanks. I think I did watch it a long time ago, but I must have forgotten.
As you can see I didn't do as much research as I should have.

Question
How to make elemental phosphorous from phosphides?
I have read that they are sold as rodenticides to mix with rat food. I'm an amateur so is there any way I can get phosphorous from metal phosphides
like calcium and aluminium phosphide? Because I cannot find elemental phosphorous anywhere. The red one along the side of matchboxes is present in so
small quantities

There are several threads devoted to isolating elemental Phosphorus on here, a quick search will get you there.
BTW, those pest control phosphides are FUMIGANTS that release poisonous phosphine gasses. MUCH more dangerous to handle than the phosphates-
So, what is your phosphorous project in relation to?
I hope your next questions aren't about elemental Iodine and/or Lithium metal? Or maybe production of methylamine?

Red phosphorus is very hard to buy as it is used extensively in the production of methamphetamine.
isolating it is no easier, but not impossible, don't expect to make it in any less than a week, and it may cost a lot of start-up money....
This is a great place to learn some of the common procedure's.

Hello, I was watching a you-tube video that said that hydrochloric acid would react with copper sulfate to form copper chloride, Sulfuric acid, and
water. Is this true?

all you will get is all the ions present in a solution and if the Cl- ion is in high enough concnetration the [CuCl4]- complex ion so while there
will be copper ion sand chloride ions present in solution they don't go around as CuCl2 in solution and the same for sulphuric acid you will have
hydronium ions and bisulphate and sulphate all as a mess in a solution. not sulphuric acid and copper chloride.

If you want to make copper chloride, precipitate the copper sulfate with sodium carbonate/bicarbonate (watch bubbling if you use the bicarbonate) and
dissolve the carbonate in hydrochloric acid. Works like a charm and can be used as an etching solution with excess HCl and a bit of hydrogen peroxide.

Question
Not a chemistry question...
I just received a big MMO plated Ti anode. It's strong as hell, and I've already broken a heavy-duty pair of wire clippers trying to cut it to a
smaller size.
Although I haven't tried, it seems like a hacksaw would be hard to use to cut a mesh. It's 10 in by 6 in - way to big for my project, and definitely
needs to be shortened. How would I go about cutting it?

An abrasive cut off wheel at high RPM. Wear protective equipment and a dust mask.

Yeah, thanks everyone, I tried sheet metal snips didn't even make a dent. Bert's suggestion is probably the most ideal, but I'd
rather not spent any more money, or wait for shipping. I didn't think Ti was even that strong... Perhaps I could use a chisel and hammer to break
every wire individually.
[EDIT] Never mind, I used a hammer on the metal snips, it worked great.
I can sell pieces of MMO to anybody that wants one. $2-4/ sq inch (Depending on the amount). Contact via U2U or email.

I don't think aluminum forms stable complexes with nitrogen donors, outside of being dissolved in liquid ammonia. Lang's handbook of chemistry
doesn't even list an ethylenediamine complex.
Please remember: "Filtrate" is not a verb.
Write up your lab reports the way your instructor wants them, not the way your ex-instructor wants them.
