| Physical Description | Chloroplatinic acid, is a reddish-brown solid. It is soluble in water and will yield a mildly acidic solution. It may cause illness from inhalation of the dust and it is irritating to skin and eyes. When heated to high temperatures it may decompose to toxic chloride fumes. It may burn, but may be difficult to ignite. It is used for manufacturing indelible ink and in electroplating processes.Dry PowderLiquidReddish-brown solid[CAMEO] Brownish or yellow crystalsDeliquescentOdorless or mild odor of hydrogen chloride[GFS Chemicals MSDS] Exists as hexahydrate[Merck Index] |

| Reaktive Gruppe | Acids, Weak |
| Reactivity Profile | Oxidizing acids are generally soluble in water with the release of hydrogen ions. The resulting solutions have pH's of less than 7.0. Materials in this group react with chemical bases (for example: amines and inorganic hydroxides) to form salts. These neutralization reactions occur as the base accepts hydrogen ions that the acid donates. Neutralizations can generate dangerously large amounts of heat in small spaces. The dissolution of acids in water or the dilution of their concentrated solutions with water may generate significant heat. The addition of water acids often generates sufficient heat in the small region of mixing to boil some of the water explosively. The resulting "bumping" spatters acid widely. These materials have significant ability as oxidizing agents. but that ability varies (for example, from high for nitric acid to low for sulfuric acid and most sulfonic acids). They can react with active metals, including iron and aluminum, and also many less active metals, to dissolve the metal and liberate hydrogen and/or toxic gases. Like other acids, materials in this group can initiate polymerization in certain classes of organic compounds. Their reactions with cyanide salts and compounds release gaseous hydrogen cyanide. Flammable and/or toxic gases are also often generated by their reactions with dithiocarbamates, isocyanates, mercaptans, nitrides, nitriles, sulfides, and weak or strong reducing agents. Additional gas-generating reactions occur with sulfites, nitrites, thiosulfates (to give H2S and SO3), dithionites (SO2), and even carbonates: the carbon dioxide gas from the last is nontoxic but the heat and spattering from the reaction can be troublesome. Acids often catalyze (increase the rate) of chemical reactions. |

Anwendungen & Verwendung
Verwenden
Chloroplantinic acid (H2PtCl6) is one of the most commercially important compounds of platinum. Its many uses include etching on zinc, making indelible ink, plating, and coloring in fine porcelains and use in photography, in mirrors, and as a catalyst.
