  • Extracting Sodium from Salt Applied Chemistry Science

    · The sodium ions just do nothing, and this is because electrons can easier be passed to water molecules than to sodium ions If you were working with molten salt, then there is no water, and then the electrons are passed to sodium ions: Na (+) + e > Na In molten salt, sodium ions accept electrons easiest

  • I searched on google Most came back with the answer: Melt it down and conduct electrolysisnot sure about melting it, as it has a melting point of 801C which I very much doubt I could get to, or sustain in my house I think if anything Iyea thats what I meant by displacement but I can't really get my hands on any potassium I think Ive come to my own conclusion that it would be preYup, is quite easy too get hold of http://wwwsmartelements/indexphp?element=Na&arg=show Or just search around Ebay for a while A goodah interesting, thanks for the linksNo problem, it seems that due to the reactivity of Sodium compared with most other elements its hard to extract without Electrolysis to do so infaHmm, yea going to buy some anyway but would have been fun to extract it myself, as i'm in a experimenting kinda mood Ah wellWell, if anything, you could just electrolyse the salt in a solution to yield NaOH and Cl2, then boil down the solution to obtain solid NaOH, meltgood point, but I can't think of any way I could realistically do that in my own house, any suggestions?Forget about making sodium in your own house You are asking for deep troubles and accidents It simply is too dangerous, unless you have some realNo, you CAN'T make sodium!
