I recently cleaned some corrosion off of my battery with a saturated baking soda solution, and noticed the resulting substance to be an odd brown color. A friend of mine tracked some of it into the house, and I'm a bit concerned regarding how toxic it might be? I've got cats, so this is specifically why I'm worried. I've been told that the corrosion is lead sulfate, and that the sulfate + the baking soda would create a reaction of PbSO4 + NaHCO3 = Pb + CO2 + NaSO4*H2O Is that valid?

Does anybody know of a way that aluminum can be smelted without using electricity? Aluminum metal was never isolated until it was electrolyzed from molten ore, but now days, could there have been an alternate, if less practical, method of extraction discovered which requires no electricity or substances produced through electrolysis? Maybe some fancy way of cheating the reactivity series using coke to displace the aluminum?

Let's say water is attracting a H atom. That's hydrogen bonding, but can this also act as ionic bonding?

so i was told that decomposition of concentrated urine will yield ammonium nitrate, if so how would one go about this and what are the yields and purities involved? i just realised ive put this into inorganic chemistry... i suppose it is in a way, unless theres bacteria involved to oxygenate the ammonia somewhere in the process... if it needs moving, admins, please feel free.

In a chem lab we had an unknown copper compound in water, we used Magnesium to displace the copper and added HCl to speed things up. The copper fell to the bottom of the beaker and we then poured the solution through filter paper to catch and weigh the copper. Once the copper was in the filter paper we had to rinse it in ethanol and acetone before putting it in the oven to evaporate everything aside from the copper(II) and the paper. Can someone please explain the purpose of the ethanol and acetone? Thanks a ton. red7

Ok, i'm attempting to make a chlorate/perchlorate cell, but i need a power supply. I was told that converting a ATX computer power supply and using the 5 volt setting would work good. Well, recently, my brother assembled a computer of his own(it was an extremely fast gaming computer), but his 700 watt power supply would not turn on unless it had feedback from the motherboard. I have picked out a 400 watt power supply off of ebay for 17$(including shipping), but i dont know if it needs feedback from a motherboard for it to work. Here is the power supply: http://cgi.ebay.com/HERCULES-400W-Computer-POWER-SUPPLY-20-24-Pin-Atx-SATA_W0QQitemZ120439458816QQcmdZViewI…

Please post your thoughts on this method for making KCLO4 I did not write this...just interested in some opinions if it would work also any suggestions on how to improve it (if possible) are welcome MAKING POTASSIUM PERCHLORATE This proceedure is a "tried and true" method. Unlike some rec.pyro postings, which are informational, or just plain speculative, this proceedure WORKS. I have used it myself to make my own supply of perchlorate - until I decided to quit because I was making it far too fast to use. This proceedure works well to make chlorates as well. The proceedure can be modified easily to make only chlorates. When using this proceedure …

Hey guys, I had a couple lectures on group theory this week, but it's only an undergraduate inorganic chemistry class and the whole concept is very abstract and hard for me to grasp, specifically once I get past the basic operations. I understand the basic applications, how to calculate the number of vibrational modes for nonlinear and linear molecules, but my problem is explaining and interpreting character tables. I don't understand what the A, B, etc. are, and I have trouble calculating their values. So my question is, does anyone know of a good resource on the web to assist me? I've looked for some but I was hoping someone on here knows something that has h…

Can someone explain to me why the d-orbitals of a transition metal when they are in a complex are filled before the s-orbital? thanks. * i also have another question* How come the maximum oxidation state of Ni does not exceed 4 since it has many more valence electrons than 4.

I know you can look on the periodic table, but if I don't have one handy, is there an equation or something that I can use? I also know that the electronegativity increases from left to right, and the farther up the periodic table you go, but I would like to find specific numbers. (to use in finding what kind of bond it is.)

Hi, can someone explain to me. or provide some good information on how a linear free energy relationship relates to a mechanism. I have found one example where: [CoX(NH3)5]2+ + H2O <--> [Co(NH3)5(OH2)] + X If log (equi constant on the x axis) and log ( forward rate constant) on y-axis, the graph has a gradient of 1. It then goes onto say that this implies a dissociative mechanism....I just dont see how that applies

Well ... I'm still working on my experiment with freezing my water for drinking when I'm out riding my bicycle (which I do a lot, as I'm living car free). This is what I've found out so far: 1) The one-gallon water containers (the ones you buy at the store) are no problem. I have over a dozen of them in the cabinet and on our pantry shelves. I only clean them with very hot water, and I check them freqently, and still have not found any of the gross stuff floating around in them. All of these containers have the #2 Triangle 2) Several square plastic containers (new from Wal-Mart) don't seem to be good for freezing water, as there is stuff floating around when t…

There is basically only 1 way to make KCLO4 that is by electrolysis. of common salt, followed by double decomposition with Potassium Chloride. But the way I make it is by electrolizing Potassium chloride and running my cell a few days after you have Chlorate to get Perchlorate. First you get a cell liquor (2-liters)of saturated Potassium Chloride. Appox. 900 grams and add about 100 grams of table salt to improve electical conducttivity. I use a Titanium cathode,and Platinum anode. Hook to DC power source of 5-6 volts and 10-15 amps,(use a heat sink so you dont have a melt down) Run cell for about 2 weeks then check for perchlorate using methelean blue. Once you have a goo…

hi there everyone, I just drew a mo diagram of c2(C=C) and see that the bond between the two carbons is a double bond and that is due to the 2p pi orbitals. so where does the lone pair come from in the dicarbon then? I reckon they come from 2s bonding and antibonding orbitals. frstly could anyone confirm that please. given that, the dinitrogen has a similar mo diagram. comparing the two, can we say that the lone pair in dinitrogen have the same energy as in dicarbon as they too come from the 2s bonding and antibonding mo'? any comment or help appreciated.

Hey everyone, I was doing some past papers and this question (see below) came up. I am not sure If my answer is correct or not, but maybe you can comment on it and tell me. Is [Hg2]2+ stable towards disproportionation? +0.91 +0.77 Hg^2+ ----------> [Hg2]^2+ ------------> Hg I would say that the [Hg2]2+ is not stable towards disproportionation as the the potentail to the right of species [Hg2]2+ on the latimer diagram is lower than the potential on the left of species. Do you think that this is right approach (qualitatively) to answer this question or might I have to use Delta G to confirm my reasoning?…

Hi! I am new to this forum. I need some help on this from you folks. In future some time soon I may have to check out Potassium Chlorate for purity.This will be done before I send this for analysis to a proper lab. I require to put together a kit to test KCLO3. Something not too elaborate and at the same time having some accuracy,so that I can decide and send it for further test in a Lab. Any suggestions ?

is there anyway to speed this reaction up at all? I`ve one reaction going for 2 years now, and I had a look today and I finaly have FeCl2 crystals. ok it was from when I was on holliday by the sea and tied a string of large powerfull magnets to a rock as the tide came in and collected the particles that stuck to it, they were washed and put in a sealed jar along with 30% HCl. now I have 30% HCl and old iron screws in there, other than making them look a little cleaner, there`s no visible signs of a reaction, I added a few drops of Nitric acid to this (literaly 3 drops in 100ml of HCl) hoping something would "kick-off", Nada I don`t want to warm it up as that…

So, I was thinking water changes state from liquid to gas at 100 degrees Celsius and becomes water vapor. So how come a glass of water left at room temperature will eventually evaporate, even though it's not hot enough?
