    I can't remember where it was, but somewhere i read that it was possible to make sodium. The process had something to do with salt, some kind of liquid, and an electrical current. Does this sound familiar or like it would work to anybody?

    In my never-ending quest to prepare inorganic salts for my various experiments in electroplating, I was attempting to prepare a small amount of Nickel Chloride by using shards of 99.9% nickel with concentrated HCl, but I guess that what's missing is some sort of oxidizer because the reaction is nil... nothing, nada! There's some very weak bubbling after an hour, but nothing to write home... no "green" color at all. A while ago, I had prepared succesfully some Zinc Chloride using the same basic process, but in that case, the reaction was vigorous and when it subsided, I had some relatively pure ZnCl2. So here I have a becher with a few grams of nickel and about 20 …

    If you had to choose ... who would be the King of the Elements ? In other words, what is your favorite element ? You can pick just ONE element. Maybe, if everyone has answered, we can nominate an element to become the King of The Periodic Table My King would be MERCURY ! The only liquid metal by room temperature, so dense and shining grey. Special but toxic. Beautiful but expensive

    Synthesis of hydrobromic acid with sodium bromide and phosphoric acid. And synthesis hydroiodic acid with potassium iodide and phosphoric acid. i was wondering how well do these to experiments work? and is there a good way to do them? ps: i know that these projects deal with very corrosive acids and toxic gases

    Hi I just want you to know that i do have experience working with 31.45% hydrochloric acid, and i know all the dangers, so i just want to know the difference of hydrobromic acid in terms of safety.

    Hi. Some basic experiments turn fluids to different colors depending on its properties, to determine its characteristics. Are the colored particles at molecular size? Dyes, inks, are their color at molecular size or just to the size of its finely ground material in suspension ? Example, fountain pen ink.

    Well i know that if you add ammonium hydroxide to copper sulfate it precipitates copper hydroxide, then with excess ammonia it redissolves to form the complex tetraamminecopperIIsulfate. So my question is, is this the same thing that happens with all copper compounds? Will copper chloride make tetraamminecopperIIchloride or copper phosphate make tetraaminecopperIIphosphate? and whats the difference? thank you

    Ammonia is NH3, or hydrogen nitride, so it would seem like it would be an acid. However, as we all know, it's a base. Why is this?

  10. Please consider the following: I have a small container of air (approx. 10 ml) and a source that is creating nitrogen dioxide by combining the oxygen and nitrogen in the container. I would like to find (and have been searching for) a means to absorb/adsorb the NO2 using, preferably, a replaceable dry filter. There is no air flow as such, in theory all of the oxygen would be combined with the nitrogen eventually leaving no oxygen. I'm not sure of the rate at which the NO2 is created, it gets to 200ppm in a few seconds. I have looked at activated carbon, soda lime and zeolite - the activated carbon has been reasonable - but if anyone has any ideas for a bet…

  12. I am aware you can purchase glycerin easily but for the purpose of curiosity I was wondering if it is at all possible to refine what is already in a multitude of everyday products into a usable volume, in this case from cough mixture. There is no application I have in mind for it, just merely asking to see if it is possible??

    hi i am planing on making around 50 or so grams of ammonium chloride from 31.45%HCL and ammonium hydroxide solution from walmart. What would be the best way to do this to get the best yield. also how should i dry the ammonium chloride?, and test it for purity?. i do not have a PH indicator. and i do not know the %of the ammonium hydroxide.

    Hi, Quick question about the preparation of Zinc Chloride... I have been attempting to prepare a small batch of ZnCl2 using zinc cut up in small strips and some HCl (25ml of 32% HCl and 25ml distilled water) in a becher. Zn + 2 HCl → ZnCl2 + H2 This is my first attempt at this and at first, the reaction was quite energetic, so I figured that when it would subside, the acid would be neutralized and the result would (mostly) a pure zinc chloride solution. But 24 hours after the beginning of the process, a strip of ph paper indicates that the content is still strongly acidic, even though the remaining little pieces of zinc have stopped bubbling. Should I…

    could someone give me some information on Tetramminecopper(II) sulfate? I already read the info from wikpedia and some other sites i just want to know about safety, and after i make and dry it can i redissolve it in water to recrystallize it?, or will it decompose into ammonia and copper sulfate?

    Hi! I'm a chem. grad student and I'm trying to prepare HCo(CO)3 catalyst from Co2(CO)8. Could I obtain this catalyst by reacting Co2(CO)8 with a hydroxyl containing compound like NaOH or KOH? If I can form the product with the OH-, would the OH- side-react with the catalyst? Let me know! Thanks!

  18. OK, instead of using hot nitric acid to dissolve old fine silver jewelry, would it work to just hang the cleaned jewelry in a solution of copper nitrate and use it as an anode? The copper would plate out on the cathode, and the silver would go into solution, right? What I'm worried about is that an oxide layer might coat the silver and stop the process. Is this method feasable, or do I need pure nitric acid? Mine's contaminated with hydrochloric that I'm too lazy to remove.

  19. Hi i have a question about predicting the reactivity of an element with an acid. So i know that copper will not react with HCL but zinc will. I know this because i put the two elements in HCL and seen that copper wont react and zinc will. so my question is how can i predict if an element will react with an acid before i do an experiment. And please don't say look it up on google, thanks. Merged post follows: Consecutive posts mergedMaybe I didn't ask that right, so I will ask the same question a tiny bit different. So for example if i wanted to know if copper would react with acetic acid, hydrochloric acid, and nitric acid, how could i figure this out on …

    I made some copper chloride out of pure copper wire and HCL and H2O2. the solution dissolved all the copper and turned dark green, so then i wanted to get rid of all the hcl that was left so i boild it till it was dry then i rehydrated it with water so i could do recrystalization to get a cleaner product. But when it evaporated there were no crystals just a real dark green thick syrupy liquid, did i do something wrong? Thanks.

    Here is a website, which cliams to have created Mineral Redox Water using Water Electrolysis by AC current instead of DC current. Is it feasible?? http://www.water-prox.com/mineral_redox_right.htm How to make Mineral Redox Water? Alkalizing ion water in the market using direct current for water electrolysis separate water to plus ion and minus ion and does dissolved minerals the same. Alkaline water and acid water separation is far different from ideal natural water. Each missing some benefits by focusing on one side benefit, which is mainly producing active hydrogen in water. Natural water contains both plus and minus ions with all good minerals dis…

  23. Hi all, I just prepared a batch of Copper Sulfate... I have prepared a solution of 60ml distilled water, 6ml HN03 and 10ml H2S04 and put a big ball of fine telephone copper wire (unsheated). The reaction was energetic and produced a beautiful blue solution. Now it has settled and there is a bit of copper left, but the solution is deep blue. Even though the HNO3 is the oxidant and most of it escapes as it turns into nitrous oxide, can there be some Copper Nitrate impurities in my CuSO4 ? And now that the solution is settled, I know that there is a bit of sulfuric acid left in the solution, what's the easiest way to get rid of the H2SO4 to get clean crystals? …
