Okay guys I know there are many threads on elemental phosphorus extraction already but... Does anybody know if the method outlined here http://www.ehow.com/how_4524329_make-phosphorus.html would work? And if so what in the world does ginger contribute to the reaction:confused:... Oh and I *might* attempt this so any other safety advice would be appreciated... Thanks in Advance!

Hello! I am doing a study on cytochrome c oxidase and am having some problems at the redox part. If the half reaction Cu2+ + e- -> Cu+ Cu2+/Cu+ = 0,153 V so, the inverse is: Cu+/Cu2+ = -0,153V Right? Thus, how the pair Cu2 + / Cu + catalyzes the oxidation of Fe2+ to Fe3+ (Eo = 0.77V). Another question: higher the spin of a complex, higher the redox potential? Right? I would be gratefull by help. thanks!!

What happens when these chemicals are mixed. Ferric Chloride + copper ? Copper sulphate + Calcium hypochlorite ? Copper sulphate + Calcium Carbonate ? Copper sulphate + Sodium Bicarbonate ?

hi can some one explain for me wish are the chemicals that are in this etching soultion that makes metall black? and what are hapening? u can se the vidio on youtube

NEVER BREATHE A GAS OTHER THAN AIR! IT DEPLETES YOUR LUNGS OF OXYGEN AND IF YOU DON'T KNOW EXACTLY WHAT YOU ARE DOING, YOU CAN GIVE YOURSELF BRAIN DAMAGE! IN ADDITION TO THIS, HYDROGEN IS HIGHLY FLAMMABLE, AND SHOULD BE HANDLED WITH CARE. OK, that being said, I have been making hydrogen for the purpose of demonstrations showing how it is the lightest gas, in which I inhale some and then talk with a very high voice. I have tried reacting aqueous sodium carbonate with aluminum, and also aqueous calcium hydroxide with aluminum. (Well, actually the aluminum is reacting with water, but it can't happen without these catalysts.) Both of these reactions take several hours to …

So, I know that acids are very conductive of electricity. However, what kinds of materials are liberated when you run a current through an acid? For example, with HCl, I imagine it would be hydrogen and chlorine, but what about sulfuric acid? How about phosphoric? I know that when ammonium sulfate is added to sulfuric acid and then electrolyzed, it forms ammonium persulfate, but what about without any substance in the acid?

Wow I have a lot of questions... OK, I just made an aluminum battery using a piece of aluminum foil for the negative terminal, and steel wool for the positive terminal. I put both pieces of metal in a container of NaOH solution. (The NaOH catalyzes aluminum's reaction with water.) Before I connected the aluminum to the steel wool, lots of bubbles of hydrogen formed on the aluminum as the aluminum ions displaced hydrogen ions in the water. But when I connected them in a circuit, though some bubbles started forming on the steel wool (giving me a current), most of them still formed on the aluminum. Steel is a resistor, which may contribute to this inefficiency, but I tried c…

well are they i have no idea

How do you get sulfur, and how do you make it into sulfuric acid? Any other strong acids that I could make if that one would be too hard? Any cool stuff I could do with strong acids? Thanks

Forgive me if this is a common knowledge question, but how does one go about producing iron, copper and/or alluminum sulfide... Alluminum sulfide is said to be produced from "ignition of the elements" and iron by "reacting iron and sulfur"?... Copper sulfide seems easy enough as I have copper powder:-) but can I use molten aluminum/ iron and sulfur or does it have to be powder? Any help would be appreciated. Thanks in advance!

So, I'm a newb, and although I saw something similar to this when I searched, I wanted to find out something... My mom wanted copper sulfate for painting. We discovered that my brother had a chem kit including epsom salt (MgSO4) and copper wire. A 25 mL 1M solution of MgSO4, a 9V bolt battery and a little wire-and-connector thing that goes with the 9 V battery later... I have a clear solution with a very light green, fluffy-looking precipitate settled at the bottom. So, what I'm asking is, what is this? The red side of the wire completely disintegrated from the wire-and-connector thing and I have no idea what kind of metal it was. Googling light green precip…

can u make it like kno4?

hi all, just a couple of points I want clarification on; 1. Orbitals in many-electron atoms are lower in energy than the hydrogenic orbital. I dont understand this bit. when the principal quantum number increases, the radial function increases, so the energy should infact increases due to increased screening effect. But this statement says the opposite! 2. d orbitals are poorly shielded so that nd orbital is of slightly higher energy than (n+1)s orbital for a gasesous element. e.g. ...4s<3d...! I dont get it, when d orbitals are poorly shielded they should be penetrating the core much better than (n+1)s orbital and experience the Zeff more and th…

I know this is a short post containing what I am saying now, but i just have on simple question and do not have any others. {Except} What Is the strongest{temperature wise}material out there? Thanks.

I have about 3-4 litres of sulfuric acid of concentration roughly 3.75mol/L, I need to use some of this because its just rediculous to have this much H2SO4. Anyone who has any good ideas on what I can do with this keeping in mind I've covered many of the quick common experiments. So I'm looking for something a bit different I don't have many other chems but can buy easy to get ones, so fire away, and help out a guy who has way to much acid. ~Scott

OK, it has been a while since I have done anything with chemicals... But I am bored and that is usually not a good thing in my case. But I figure playing with chemicals may be a little safer for my wife's sake then playing with electricity since 230v does make a pretty nasty pop when you do not ground something right Anyway, I have been playing around and making crystals. I have done some sugars and various salts and even made some boron crystals but that ended up becoming a very big mess. I wanted to make something nice and while researching, the copper sulfate crystals caught my eye; until I saw the toxic hazard warning which is not a good thing when you have a…

I have some potassium manganate that I'd like to convert to the permanganate, but so far, every single one of my attempts has failed. I heard about electrolysis of the solution, but all it ended up producing was manganese dioxide. Any suggestions...?

I'm currently doing a project for my calculus class involving doing calculations with flash powder. It has been a while since my last and only chemistry course and my teacher was anything but competent... I can't recall how to find out how much energy is released from an exothermic reaction or how to find the activation energy or anything of the sort. Any help would be appreciated. I'm using [ce]5KNO3 + 3S + 2Al[/ce] flash powder.

Would it be possible to synthesize Ba(OH)2 from an aqueous solution of sodium hydroxide and barium chloride. The reaction would look something like: BaCl2 + 2 NaOH --> Ba(OH)2 + 2 NaCl Because Ba(OH)2 is not nearly as soluble as the other salts, it would fall out of solution - not all of it, but some of it. Now, if I was to use something like barium acetate, that wold be far more soluble in water (about 66 grams per 100 ml vs. 37.5 grams per 100 ml) and this would mean I could add more barium ions to less water, and therefore get more barium hydroxide out of the solution (due to less water, and more barium) So, my reaction would look like: Ba(CH3COO)2 + 2 NaOH …

How do ice crystals chemically form? I was curious, i know that water expands when frozen, but what makes it actually expand? Thanks.

Hi everyone I'm planning an experiment to make prussian blue, from scratch. The part going from K4Fe(CN)6 to prussian blue is easy peasy, I can find alot of literature on this. But going from iron (II) sulphate to K4Fe(CN)6 is a little harder for me to find information on. Anyway, using my mind (a dangerous thing!) i figured that FeSO4 in water, then add KCN and some acid, with some heat(90 deg.C ?) and then letting it cool, the cyanoferrate i want will fall out of solution. Would this actualy work? Or am I barking up not even a tree, let along the wrong tree? Matt

I`m awaiting shipment of 100g of red phos, I was wondering if there`s a solvent for it? White phos will dissolve in some oils quite easily, I`ve just tried RP in Methyl benzene (as it works great with Sulpher), it doesn`t appear to have done anything at all, even upon heating to boiling point. polar and non polar solvents at face value don`t seem to have a great effect upon RP. and I don`t want something that`s going to react with it, just dissolve it. any thoughts?

Hello, I want to convert hard water to soft water by the process of electrolysis. Hard water contains chlorides and sulphates of calcium and magnesium and bicarbonates of calcium and magnesium. Anybody got the idea of how to remove these salts by electrolysis can help.

2Mg + 2NaOH -> 2MgO + 2Na + H2 Aqueous solution of NaOH or something else?

I`ve been working on a way to obtain elemental Phosphorus. naturaly I`ll convert it to Red P4 rather than store it as White P4. so far the best way I can come up with is the conversion of Phosphoric acid with Carbon and distilling it. the starting chems I have, are many, Ammonium phosphate, calcium hydrogen phosphate as my 2 sources. does anyone know an easier method from the above? all the other chems that may be required I should have, so don`t worry about having to think of complicated ways, complex is good too, so long as it works maybe an electrolytic way? or a way that doesn`t require distilation? Ideas please
