Zink chlorid electroplating?

  1. Feb 15, 2007 #1
    Hi!

    Dunno if this is the right place to ask but here goes:

    One of these electrodes have a 'white layer' on it.
    My questions are, could this be "electroplating"?
    And could zink-chlorid acid do this?

    I hope somebody knows, it means alot to me, thx!

    It is probably electroplating if you have applied a current through the electrodes. The electrode with 'white layer' is the cathode. The anode will be dissolved into the electrolyte and if that is not made of zinc, after a while the electrolyte is not pure zinc chloride any more.

    Thx!

    Well, I havnt applied a current thru them, but the question is, have the ancient Egyptians or Zulus?

    You see the picture is taken by a robot sent in the the northern shaft of the "queens chamber" in the Great Pyramid of Giza. The other shaft, which is a perfect copy, also has 'electrodes' in the end, but no white layer.

    It would seem that the two shafts leading down to the 'queens chamber' would have contained fluid.
    Early explorers said the room smelled and reported a layer of salt on the walls and ceiling. The shafts were not cut thru to the chamber, stoppen a couple of inches short, so that the acids could filter thru the limestone and react with the salt.
    The electrodes would be level-indicators so they would always know when the shafts needed filling (there are two "weird" wells outside pyramid)

    So one shaft would have diluted hydrochloric solution, the other zinkchlorid acid.

    These two acids, when they react with salt, that creates hydrogen is that correct?

    The pyramid would then fill with hydrogen, because its blocked with granite at the entrance.

    The Giza Powerplant?

    Zinc chloride is a salt, not an acid. Acids reacting with salts do not generally make hydrogen, though acids reacting with bare metal will do that.

    We need more information. Do you have links to the original source?

    Anyone see any problem with zinc chloride solutions (pH 4) in limestone tanks?

    ZnCl2(s) <------> Zn+2 + 2Cl-
    Zn+2 + H2O <-----> ZnO + 2H+


    What kind of acid would filter through limestone and then react with zinc chloride? One limestone shaft containing dilute hydrochloric acid? And the other limestone shaft containing zinc chloride solution? Really! What gas might you expect to have been given off under these conditions?

    Hint: The field test for carbonate rocks is the application of hydrochloric acid. Something is observed. Can you guess what it might be?

    Perhaps the "fluid" contained was atmosphere?

    Was the salt on the walls sodium chloride?

    What does it mean when your name has a line through it?

    It usually means the member has either been banned for violation(s) of forum regulations, or has requested to be removed.

    In an earlier post (now deleted), Mad.Arsenal provided several links to crackpot sites owned by a person that claims the ancient egyptians were interstellar travelers who possessed highly advanced technologies.

    Typically, a post of that nature is deleted and the member warned against refering to crackpot sites and/or supporting crackpot claims. If the member does not heed the warning, s/he risks getting banned for it.
