      No. An example would be if a precipitate formed in a colorless solution that remained colorless.

    (Mg) or (mgcl2) in aqua regia = Dissolve or not

    • @DrRichardMusgrave
      @DrRichardMusgrave  Před 4 lety +3

      Aqua regia is a mix of concentrated hydrochloric and nitric acids. I would say that the probability is high that both Mg and MgCl2 would dissolve in it.

    Should magnesium be in excess?

    • @DrRichardMusgrave
      @DrRichardMusgrave  Před 4 lety +1

      Mg may be in excess, with the dilute concentration of HCl that is being used here. If concentrated HCl was used, it would dissolve all of the Mg quite quickly. This would be a lot more dangerous, however.
