Inorganic Chemistry

Hey guys. I'm back to SFN with a very boring issue. I'm doing some pretty nice copper electroplating on stainless steel pieces using a solution containing 250g.L-1 CuSO4.5H2O, 0.05 mol.L-1 H2SO4 and 0.1 g.L-1 SDS. As it is for codeposition of suspended particles, it is desirable to use a dispersant (SDS) and EDTA. I usually use a temperature of 28°C (82ºF) that is mostly related on the articles I've seen, but somehow, when I used a temperature of 50°C (122°F) which is still OK for this kind of electroplating and took the sample to EDS analysis on a SEM, there was a big peak of Cl (15% wt. of the surface). Question is: WHAT THE HELL IS CHLORINE DOING HERE? I do…

if an oxygen ion radical (or whatever you call it) came into contact with a water molecule would it react to give a hydrogen peroxide molecule?

ok, so after watching the Mythbusters launch the "civil war era" hybrid rocket, i wanted to make a very mini model rocket that works myself. after some research it became quite apparent that although the fuel part of a hybird rocket (paraffin) is easy to find (PS idk yet if the common grade found in the market is able to sustain combustion but i will look into that a bit after solving the oxidizer issue) getting your hands on a liquid or gas oxidizer in such small quantities is quite difficult, not to mention hard to handle (hard compress oxidizers enough to hold it in liquid form). after finding about hydrogen peroxide i decided to try and see how it works. i bought…

If you have a solution that's a mixture of Magnesium salts (SO2-, Cl-, NO3-, F-) and then add any of one of the more reactive metal salts (CaCl, CaNO3, etc), which is going to be the most prominent Ca salt formed in a metathesis reaction? Is there a particular order to which anion is more stable with the more reactive metal? Thanks for the help

in inorganic chemistry when we define a surface, how many molecular layers/ or 'depth' are we talking about.

would atomic oxygen react with a water molecule, on contact, to give hydrogen peroxide? (if i've got it wrong again i mean a single oxygen atom ion thingymajig, not combined with another oxygen atom)

will nitrous oxide oxidise nitric oxide to nitrogen dioxide? given heat perhaps

hello i am student of class 7th .i was thinking what will be the substance yielded as a result of chlorine +"X"=bleaching powder....what will be X

Is there any way to concentrate dilute nitric acid to its azeotropic concentration of 68% by freezing rather than distillation? That is, would either the water or the azeotrope solidify out, leaving behind the other in liquid form?

''For classroom demonstrations, silane can be produced (temporarily) by heating sand with magnesium powder, then pouring the mixture into a 20% dilution in non-aqueous solution of hydrochloric acid. If silane contacts with water it will react violently. The magnesium silicide reacts with the acid to produce silane gas, which combusts on contact with air and produces tiny explosions'' - if this was repeated in a helium atmosphere would the silane be kept?

hey, I recently bought some Amazing! liquid fire drain unblocker with concentrated sulfuric acid. it's a dark brown oily liquid (which I think is what normal sulfuric acid looks like) I was wondering if anybofy knew the concentration, purity or the "nertness" (as in not inert) of the other chemicals that could possibly be in the drain cleaner. thanks in advance.

So i know that Sodium bicarbonate (NaHCO3) + Hydrochloric acid (HCl) ==> Sodium chloride (NaCl). So what i want to do is make some crystalize it and see if it tastes better or different then normal table salt. It seems to me like this would be safe to do but just to be sure would tasting homemade salt be ok? Thanks by the way i do have experience HCl.

elementary tests provide us the rough idea about the compounds. what can be the best steps to be taken or what are the best possible procedures for it?

I know that morh's salt has many uses, one of which is medicine, but my questionis what exactly does mohr's salt do within medicine? i haven't been able to find out. if anyone can help me out it would be much appreciated.

What is the easiest ways of creating some magnetic fluid without ordering lots of expensive chemicals on the Internet? Is it possible to create out of normal things found in the house or almost any store? I have some iron-powder if that is needed. Thank you in advance Sorry for my bad English :/

Just that, can a solution of chlorate be converted to perchlorate using hydrogen peroxide? ClO3- + H2O2 = H2O + ClO4- Guess this is just a question of H2O2's strength as an oxidiser compared to chlorate? Or to perchlorate, because the product, perchlorate, is more stable than chlorate, would this drive the reaction to completion? Thanks

I'm trying to synthesize sodium aluminate from NaOH and old pop cans, but when the reaction goes it produces a dark gray solution, when it should theoretically be clear. Is this because of an impurity in the aluminum? Why do a lot of aluminum reactions like this produce dark, gray sludge? Thanks for the info.

Well basicly i was on wikipedia and stumbled upon this http://en.wikipedia.org/wiki/Sextuple_bond .My only question is, are they real, and if so why do they work it sounds like way to many electrons to me.

I'm looking over synthesizing alcohols with grignard reagents. I'm going batty trying to figure out where the positive charge is on MgBr+. Is it on the Br? The Mg? Is it localized all over, as in [H3O]+? Thus being [MgBr]+? Also, what is the name of the MgBr+? ChemSketch didn't seem to help in this department.

is there to mix some chemicals to make a chemical reaction that would make it glow (like bioluminescence or glow in the dark) and could this be added to paint in some way to make a surface that would be more visible in the dark?

I worked out a method for making Cryolite with easily available home chemicals (though I never tried it, and I don't recommend so), namely: 1) Sodium Hydroxide. 2) Any Aluminium Compound 3) Not really "easily" available: an adequate supply of hydrofluoric acid (HF) The method should go on like this: 1) Aluminium Compound + NaOH => Al(OH)3 +..... 2) Al(OH)3 + 3NaOH => Na3Al(OH)6 3) Na3Al(OH)6 + 6HF => Na3AlF6 +6H2O. Any viewpoints are accepted, it's just a question

hiii guys... plz tell me how can i make zinc chloride commercially....... is ant equipments is require for making of ZnCl2. plz help me.............thanks in advance

i have three beakers each have diff %of HCL .....how i can find that which one is 30%of HCl, which one is 200%of HCl and which one is 10%of HCl. plz help me to find it my basic aim is to find the HCL %

How come when u dissolve salt in a liquid it occupies the space between the molecules of water after a certain extent the salt stops dissolving because there is no space between the water molecules so why doesn't the water turn to solid

Howdy good folks, I've gotten myself into a bit of a conundrum. I need some copper plating on an aluminum alloy surface. My chemistry is about 20 years rusty, but I understand this is meant to be "difficult" to "unpossible" with a simple CuSO4 electroplating setup. However, I remember achieving a reasonable plating on aluminum before, many years back, when I was a kid with a model train transformer and a bag of CuSO4... So, been looking around here and on the rest of the net for tips... it occurs to me that I could use some method not regarded as commercially viable, either due to time factors, or current consumed or whatever. I don't really care about the …
