  2. Adams' catalyst - Wikipedia

    en.wikipedia.org/wiki/Adams'_catalyst

    Adams' catalyst is prepared from chloroplatinic acid H 2 PtCl 6 or ammonium chloroplatinate, (NH 4) 2 PtCl 6, by fusion with sodium nitrate. The first published preparation was reported by V. Voorhees and Roger Adams. [2] The procedure involves first preparing a platinum nitrate which is then heated to expel nitrogen oxides. [3]

  3. Ammonium hexachloroplatinate - Wikipedia

    en.wikipedia.org/wiki/Ammonium_hexachloroplatinate

    Ammonium hexachloroplatinate is used in platinum plating. Heating (NH 4) 2 [PtCl 6] under a stream of hydrogen at 200 °C produces platinum sponge. Treating this with chlorine gives H 2 [PtCl 6]. [2] Ammonium hexachloroplatinate decomposes to yield platinum sponge when heated to high temperatures: [2] [5] 3(NH 4) 2 PtCl 6 → 3Pt(s) + 2NH 4 Cl ...

  4. Aqua regia - Wikipedia

    en.wikipedia.org/wiki/Aqua_regia

    As a practical matter, when platinum group metals are purified through dissolution in aqua regia, gold (commonly associated with PGMs) is precipitated by treatment with iron(II) chloride. Platinum in the filtrate, as hexachloroplatinate(IV), is converted to ammonium hexachloroplatinate by the addition of ammonium chloride. This ammonium salt is ...

  7. Transition metal nitrate complex - Wikipedia

    en.wikipedia.org/wiki/Transition_metal_nitrate...

    Being the conjugate base of a strong acid (nitric acid, pK a = -1.4), nitrate has modest Lewis basicity.Two coordination modes are common: unidentate and bidentate.Often, bidentate nitrate, denoted κ 2-NO 3, is bound unsymmetrically in the sense that one M-O distance is clearly bonding and the other is more weakly interacting. [2]

  8. Chloroplatinic acid - Wikipedia

    en.wikipedia.org/wiki/Chloroplatinic_acid

    Chloroplatinic acid (also known as hexachloroplatinic acid) is an inorganic compound with the formula [H 3 O] 2 [PtCl 6](H 2 O) x (0 ≤ x ≤ 6). A red solid, it is an important commercial source of platinum, usually as an aqueous solution.
