    24/01/2006· HCl (or any other other acid) only reacts with oxides at an appreciable rate if they are not calcined or crystalline. HCl indeed reacts (slowly) with fresh rust (hydrous Fe2O3) or freshly precipitated Fe(OH)3. The solutions formed this way are not green, but bright yellow, due to formation of the complex ion FeCl4(-).

  • Over the summer I used some very powerful neodymium magnets to obtain some magnetite, with the hopes of being able to purify it to thermite-grade (...umm generally you wouldnt see a reactionwhen you add hcl to rust nothing happens, at least visiblyAfter a few days, you would notice that the rust was gone...Are you kidding? Maybe you should try it for yourself. You should actually observe a steady reaction between rust and HCL. The rust will dissolve a...But what about Fe3O4?HCl (or any other other acid) only reacts with oxides at an appreciable rate if they are not calcined or crystalline.
