1) let it sit and filter the gypsum with a polyester/polymer fabric before distillation 2) even a small car battery contains several liters of sulfuric acid at density ~1.280 when charged (in case you can't buy it directly; people sell old batteries cheap sometimes)
Nice video! I did something very similar but with a GIANT 400W ballast for metal halide lamps which I managed to get from school (they were switching the street lights to LED). Works great!
The clay in oil bonded molding sand (ie Petrobond or K-bond) isn't regular bentonite clay, it's been chemically modified to absorb oil the way normal bentonite absorbs water. A catalyst is also used to help the "organoclay" absorb the oil. So if you use oil instead of water to temper your bentonite based greensand, you might be able to make a mold with it... but it probably won't have a lot more green strength than those sand castles you mentioned. It's difficult but possible to find the right "organoclay" and oil to make your own oil bonded sand, but the organoclay can bent tricky to find in small quantities. So if you're going to all that trouble it makes sense to get the right sand too. You need the right grain shape and size distribution if you want to match the performance of real Petrobond. The sand can be trickier to source than most people think. Agree that beginners don't want to buy a heap of molding sand (and build a sand muller) are better off making small batches of greensand.
Its cheaper to buy it. It's sometimes used as a food preservative or more common as a fertilizer. But you could mix potassium carbonate with nitric acid, but that's not safe.
No miten sitä tehdään? Typerä video missä vain hierotaan hiekkaa ja läpistään asian vierestä. Meinasin tilata kanavan mutta peruin päätöksen saman tien. Miksi katsoa sellaista missä pitäisi jotain kertoa mutta ei haluta kertoa mitään 😂
Damn! Wish I had found this 10 years ago - thanks for the detailed workings of the equilibrium, so sparsely diluted in most other 'chemistry' channels 👍
Hey, great vid! was wondering how you went about the waste disposal--I'm not sure what to do and I don't want to start any projects without knowing how to finish them. Thanks!
Dude, this is really interesting, but you talk so freakin' fast that you're hard to follow ... and I speak the exact same dialect of English you do. If you talked slower, this could be outstanding
What you make here is called Supersaturation solution which means dissolving the maximum amount of substance in the water…if you want to get pure Chrystal you need to add more distilled water, than after cooling , the kalium nitrate crystals clearly droppings to the bottom of the solution, you can pour out and collect those crystals but in your case because the solutions is Supersaturation, once you stopped heating , crystals are forming everywhere quickly, makes no chance to separation the Impurities ..
God loves all of us so much He came in the flesh to die and rise so that if we choose to accept Jesus as our one true Savior turning from our sins we may be gifted eternal salvation through Christ’s perfect sacrifice on the cross. Have a great day
I tried this on some drain cleaner HP -- and it reacts furiously with MnO2 or permanganate, I made some MnO2 from the permanganate to do this test (dirty hassle) -- but I got odd results. The first ml reacted with evolution of steam & finished before I could get the stopper on the tube -- so I got no displacement. Now maybe my reasoning is flawed -- but I figured I could just re-do the test b/c the MnO2 is a catalyst & won't get consumed -- while the first test presumably completely reacted the peroxide (I only made enough MnO2 for one test). Well the second test consisted of adding 1 more ml of peroxide to that same tube & the leftover contents that had the MnO2 & the presumably spent peroxide -- but this time I was very quick to get the stopper on and I got an amazing displacement of 110ml. That sounded too good so I did the same thing again -- add 1ml of peroxide to the same tube for a 3rd time -- this time the displacement was 220ml -- as if there is an additive effect each time I add 1ml. Is my procedure flawed or do I have awesome H2O2? I doubt that I can buy 65% H2O2 as drain cleaner. The MSDS sheets I looked up are inconsistent: one says that this brand (Pequa Super Cess-Flo-P-101) is pure H2O2 30% with no additives, another says it is between 10 & 30. The price & availability at Home Depot were super -- a gallon for $27.
Turns out my test was flawed. By using the same tube that I used to evacuate the air in the cylinder to also fill it with O2 generated, left over water in the tubing threw off the results by siphoning the fluid in the cylinder. With the use of a second tube at the entrance of the cylinder I consistently got 94 ml O2 for 1ml of the peroxide - I'll call it 28.5% -- and the deal for this product was fantastic!
