    Silver ion (or argentation) chromatography is based on the characteristic property of unsaturated organic compounds to form transient charge-transfer complexes with transition metals in general, and with silver ions in particular [211–213].Suitable electron donors are organic compounds containing π-electrons in various kinds of double and triple bonds, or containing heteroatoms

  • Silver Chemical Stability - Inorganic Ventures

    Silver Chemical Stability. By Paul Gaines, Ph.D. Many chemists often ask us about Ag chemistry. The fact is that silver is a relatively trouble-free element, provided it is kept away from HCl. We tend to keep Ag + solutions in nitric acid because these solutions are stable to photo-reduction. However, when HCl is added, two things can occur.
