Inorganic Chemistry

Why is it that any time you post something asking a question about anything interesting that may be considered dangerous moderators shut your thread down? Surely its better to give the info out and then let us decide whether its something that we want to try at our own personal risk? someone answer me, especially if you're a damned moderator. Thankyou.

how good of an oxidizer is powdered sodium percarbonate? It's available very easily as detergent/stain remover. First off, its 2 sodium bicarbonate molecules in crystalline structure with 3 hydrogen peroxides. It releases 3 hydrogen peroxides in water. We all know hydrogen peroxide is a good oxidizer, so say if you mixed powdered sodium percarbonate with powdered aluminum, would you get a thermite type reaction? Also, if you mix it with only a tiny amount of water, can you get like 50% H2O2?

Hey im having trouble understanding all the mechanisms of the following !! " A dry cell is contained in a zinc housing that acts as the anode. the other electrode, the cathode, is a graphite rod in the middle of the cell. a layer of manganese oxide and carbon black surounds the graphite rod, and a thick paste of ammonium chloride and zinc chloride serves as the electrolyte. The cell reactions are: Zn(s)-> Zn^2+ + 2 e^- 2MnO2(s) + 2NH4^+ + 2 e^- -> Mn2O3(S) + 2NH3(aq)+ H2O Pls explain: 1. the role of all the chemicals (those directly involved and what the carbon black does). 2. .... Cant remember Thanx !!!!

Helo How are you ? My question is in the picture attached . Please clarify the answer . Please explain why the answer . Thank you for forum .

Hi, I was just wondering why Fe+2 will usually form complexes which have an octahedral geometry while Co+2 will form a tetrahedral complexes. Is there a way from which we can tell that a following metal ion will form what type of complex? Can we use the Valence bond theory to do it?

hello! SiCl4 reacts with water but CCl4 doesn't. why is this so? is it because Si has empty d orbitals? but then, could someone let me know that after O attacks a d orb, why does an sp3 orb's Cl leave? please explain the mechanism in a bit detail... thanks in advance. waiting in anticipation.. :-)

Hey there, I'm looking for a catalyst other than V2O5 which can be used to catalyse the reaction: 2SO2+O2-->2SO3 So far I've considered.... FeO, I think something like this might happen: FeO is unstable below about 800 centigrade, so 3FeO <--> Fe2O3 + Fe 4Fe + 3O2 --> 2Fe2O3 Fe2O3 + SO2 --> SO3 + 2FeO But I'm also worried that this might happen: 2Fe2O3 + 6SO2 + 3O2 --> 2Fe2(SO4)3 I also thought about using manganese dioxide: MnO2 + SO2 --> MnSO4 (I'm sure this bit's correct, wikipedia says so xD) MnSO4 --> SO3 + MnO (That's a hypothetical thermal decomposition reaction... not sure if that takes place) 2MnO + O2 --> …

Hi guys, I was just wondering whether if I can use ordinary paraffin wax to burn and create thrust? Thts because I am looking for an alternate method to making rocket fuel.. KNO3 I cant find it anywhere in my country(Singapore).. So any clues?

i came acroos a reaction of phenol with Br2 in the presencs of HSbF6. the answer was m-bromophenol. could someone explain me the mechanism? please? also, could anyone tell me the properties of this reagent? and about any similar reagents? please help me out...

Hey, will anyone please explain to me how to do this equation and to determine which products will form? Thanx in advance

So i decided to grow some silver crystals. The conventional way is dissolve [ce]AgNO3[/ce] in water and put in copper, then the copper dissolves to make copper nitrate and the silver precipitates out. I figured that i would just dissolve silver in nitric acid myself... So my question is this: do I need to separate the [ce]AgNO3[/ce] from the nitric acid or could i saturate the acid with silver then just put in the copper?

Ok, again, in my search for sodium, as my last thread was shut down by the moderator and i can't generate the heat needed to make Sodium from liquid Sodium Chloride, Is there any way of getting sodium (by SIMPLE electrolysis or anything else that doesn't need something more reactive than sodium to get rid of it) out of Sodium Hydroxide that i've obtained fro the electrolysis of aqueous Sodium Chloride? Cheers.

how pure can potassium chlorate be made from sodium chlorate and what is the best method to do so?????????/

Hi, I put some small pieces of copper wire into hydrogen peroxide and let it set. The peroxide turned brown and I couldn't notice any corrosion of the copper. Any idea what this could be? I thought maybe copper oxide but the color doesn't match. Also I heated it before I let it set if this affects anything. Thanks

I want to obtain Magnesium metal for my experiment. Powder would be best. Where can I get Magnesium metal free or at minimum cost?

I am planning on making some electrolyte solution for an electroplating experinment. I have one question, How can I make copper sulfate, or a sulfate of any metal from simple household items?

I'm looking for a way to get some kind of reasonably reactive nitrate for a reaction ... either that or dilute nitric acid. Does anyone know where i can get them in the UK, in decent extractable concentrations if they're in solution, or in thir pure form? thanks Merged post follows: Consecutive posts mergedAlso, if you used sodium nitrate and KCl, how would you part the two in the resultant solution? (as this is what i am aiming for)

went to walmart today...(which is a store, for all you non-americans)... found a bottle of 99.5% anhydrous glycerin http://www.walmart.com/catalog/product.do?product_id=10417582 would simply reacting it with nitric acid yield nitroglycerin? it seems like each OH group is replaced by an NO3 group... and the rest is C3H5... for any other acid, i would say C3H5 is not more reactive then hydrogen, it could not steal its NO3. but nitric acid operates on a whole different level than other acids. often it is more than willing to nitrate something less reactive then hydrogen, i.e. copper. but that's a whole different story. not that i'm very interested in e…

Hi, Does anyone know of any good papers talking about adhering metals (Al, Ti, Cr, Au) to Gallium Phosphide? Or does anyone have any suggestions? Thanks!

What should i use for the anode and cathode in the electrolysis of NaCl - two Carbon or something else? Regards

Greetings. Not long ago, I was conducting a simple electrolysis experiment, performing electrolysis of water, using a voltage of approximately 13- 15 volts, in a saturated aqueous salt solution. I chose to use a magnesium anode, and a copper cathode, to my surprise, a substance, faintly green in colouration, began to rise from one of the electrodes. Fearing this was chlorine, I quickly disbanded this setup, building a different one, in which the reaction would take place in an erlenmeyer flask, with a holed stopper. Through the hole in the stopper, I placed a curved glass tube, which would release any gases made in the reaction, into a separate vessel. The wires connect…

I've currently been thinking of performing various reactions, using acetic acid to precipate several of the reaction products turning them to acetates. As per, doing so, requires one to actually have acetic acid on hand, so my question is, how can one produce acetic acid? I understand that vinegar is about 10% acetic acid (well, the concentration may vary...), so might there be any way to distill this from vinegar, based upon its othe components (ie water, spices, etc.)

Is there any substitute for HNO3 In the manufacture of Aqua Regia? Also, what's the easiest method of manufacture for the HCL in Aqua Regia? Does anyone know how to turn NH4NO3 back to HNO3, or separate the ammonium phosphate from the nitrate? Why bother adding 54% Ammonium Phosphate, when they know that eventually we will find a way of separating the two! Any help on these matters would be appreciated,

How can i produce Acetylene from Acetic acid?

do you guys think that it is possible to let Ar to undergo some reactions as Kr and Xe does? Do you think that a very reactive element does so?
