is there a good way to make coper (i) oxide using electrolysis and / or household chemicals? i want to do some solar experiments with it, but not the 'baked' copper plate thing. i want to tinker with it. i get at best a small amount from saltwater electrolysis, can i do something to encourage its formation, or convert copper(2) oxide to copper (I) oxide somehow??? thanks.....

Does anyone know a way i could synthesize some sodium nitrate. I plan to make some nitric acid by reacting sulfuric acid with sodium nitrate and i dont have sodium nitrate. I have tons of reagents. Maybe some reaction with KNO3 or other nitrates? I dont know, but thanks for your responses.

What would the the approximate position of silicon on the reactivity series? p.p.

Can any one explain the mechanics behind why HCl dumped into a bucket of snow will quickly reach -42 degrees F yet shaved ice will not get there no matter how hard I try. My general hypothesis has to do with hydrogen bonding, or lack there of anyway, with snow compared to the structure of ice but was woundering if anyone had more insite into this then my self. ~Sedit

Ok, I'd like to extract sodium metal from Sodium Chloride, but I do have a few problems with the electrolysis of molten Sodium Chloride, a few of which are that: A. I have no idea where to get Calcium chloride from to reduce the melting temperature of the Sodium Chloride. B. I dont have the means to heat anything up to 600*C, and have no idea where to legally get a bunsen burner other than online in the UK, as I dont have a credit card. Also, I have a query about the method that involves the electrolysis of aqueous NaCl, which is; How would you prevent the formation of Sodium Hydroxide &c after, or indeed during, the electrolysis?

Hello, I am new here on the forum, I am Brazilian and I am 13 years old, seeking a response that intrigues me about chemical reactions (I am almost sure that is part of inorganic chemistry), we know the reactions are done at room temperature (25 º C) and pressure of an atmosphere, where these levels are altered, the changes in the reactions. For my theory, some molecules are cut, because the level of photons that increases the heat, change the number of electrons in atoms of eletrosfera, making the change of ionic and covalent bond or molécolas crystals. My theory is right? We could comment more on a subject? And excuse me for using bad English xD

What would be a good cheap and or easy way to safely turn a small bin of lead oxide powder mixed with tin-lead into something that was safe? and/or what do they do with all the recycled lead from batteries and would this provide a clue to the above question? and/or can it be disposed of just like batteries or alongside a battery? it is coming from a flow-solder re-work station that has been collecting up for a while now so there is a tin-lead alloy mixed in as I am not very careful to keep all the solder out when I skim this crap off the top. I noticed some dude in here was trying to make fireworks with the stuff... maybe I can mail it to him... :…

hi guys, can you please suggest some reaction to distinguish Cuprous chloride from Cupric chloride.

So I’ve just gotten a new container of sulfuric acid, but it has a black inhibitor in it (see below). I'm having real trouble, its frustrating because the distillation is terribly inefficient, and I was wondering if I could get some suggestions on my whole setup. I've been trying to get the acid over without the inhibitor, and it has certainly been working, but I would like to speed it up a little. So here is my overall setup: As you can see, I have a 1000 ml RBF leading to a three way joint (top part is stoppered). I decided to tilt the RBF so that it is at about a 30 degree angle from the ground in order for the vapor to more easily go down the liebig c…

I cann't find how to compound sodium nitrate on the net. How do I do this (for a honors chem report & project) ? I did find one process that resulted in silver oxide and sodium nitrate but I don't know how to seperate it, how is this done?

I'm thinking about getting some bismuth trioxide and trying to turn it into elemental bismuth (trying to start a element collection). Would this be very hard? Is there anyone out there that can put me on the right track for going about this? Thanks for any help.

recently in gravimetric experiment i made nickel dmg complex which was red coloured. i left it in dessicator for week. i turned white(yellowish). while trying to wash the crucible(filter used in gravimetry) as soon as i poured water it turned red again. whats happening

Hello, This is my first post here... I've been a lurker for quite some time, but now the time has come to ask my first question! I know this is not a mineralogy forum, but a really strange thing happened and that's definitely something chemistry-related so I thought you might know! It's something I had never heard about before, and Googling about it didn't return anything. So, basically, I have a small but quite varied minerals collection. I keep all my minerals in medium-sized transparent plastic boxes; usually 2 to 5 minerals are placed into a single box. In one of these boxes, there was a large piece of what was told me to be antimonite (Sb2S3) together with a larg…

I have some magnesium turnings but i want magnesium powder. do you think it's safe to grind it in a mortar and pestle? do you think it'd work?

I am looking for somewhere to get KCl. I need it in a relativly pure solid. I have acess to basic chemistry equitment and cannot buy anything off the internet. Thanks! Zach

please could you tell be how to make aluminium powder at home

Does Hydrogen have a disassociation frequency such as chlorine does to generate the radical? And if so what frequency range would it be in?

I need to work out a perctange yield for my experiment, however i am having trouble balancing the equation. H2SO4 + C6H5Br + HNO3 --------------> C6H4BrNO2 + H2O this is what i have so far.. but there is no S on the right side of the equation.... im very confused.

Is it likely that one could produce a salt KSbFeO4 Any ideas? ~MINUS

Accorind to the table of standard electrode potentials, it is easier to reduce a hydrogen ion than a transition metal ion, such as nickel or zinc. Yet, sources such as the Electrochemistry Encyclopedia for nickel, and here on page 9, for nickel, cobalt and zinc. So, why are the metal ions reduced as oppose to the hydrogen ion?

is there any kind of database for eutectic points/phase diagrams? thanks!

ok this is from a past-paper; Describe the different ways in which the electronegativity of an element has been defined. I don't know what to answer. I think maybe the question is asking about the pauling, mulliken and allfered-rochow electronegativity values but i can't be sure. Any help on what the question is asking and what should i write.

what would you do with it? Ive just discovered i have several dozen vials, each containing 1 g of germanium. I wonder if there's anything exciting i can do with it?

in episode 7 mythbusters have put 2 dead pigs in a car fore months. then they tryed to clean the car. now i wonder if Ozongas would have worked. http://understandingozone.com/uses.asp Air Purification, Water Purification, Deodorization, and Food Sanitation Whether it's harmful fumes, chemical gases, odors, or any other scented air pollutant, ozone destroys virtually all airborne and water type pollutants!

They are also found in some major hotel chains, they use them to convert…
