Chemical Properties
YELLOW CUBIC CRYSTALS
Chemical Properties
Ammonium chloroplatinate is an orange-red
crystalline cubic solid or yellow powder which decomposes
when heated.
Uses
Platinum plating; manufacture of spongy platinum.
Uses
Electroplating of platinum, manufacturing of platinum spongeAmmonium hexachloroplatinate(IV) is used in electroplating of platinum and to make spongy platinum. It reacts with copper(II) acetate and hydrogen sulfide to prepare Cu2PtIIPt3IVS8 which finds application in diamagnetic materials and semiconductors. It is also used in platinum plating. Further, it acts as an analytical reagent.
Definition
ChEBI: Ammonium hexachloroplatinate is an ammonium salt comprising separate ammonium cations and octahedral [PtCl6](2-) anions. It contains a hexachloroplatinate(2-).
Flammability and Explosibility
Not classified
Safety Profile
Poison by inhalation and ingestion. Human pulmonary system effects by inhalation. See also PLATINUM COMPOUNDS. An explosively unstable compound. Incompatible with KOH (boiling with alkali yields a product which, after drying, will explode @ 205' or if mixed with combustibles). When heated to decomposition it emits very toxic fumes of Cl-, NOx, and NH3.
Potential Exposure
It is used in photography, platinum
plating and in the manufacture of platinum sponge.
Shipping
UN3288 Toxic solids, inorganic, n.o.s., Hazard
Class: 6.1; Labels: 6.1-Poisonous materials, Technical
Name Required.
Incompatibilities
This material is unstable and potentially
explosive. Incompatible with strong oxidizers (chlorates,
nitrates, peroxides, permanganates, perchlorates,
chlorine, bromine, fluorine, etc.); contact may cause fires
or explosions. Keep away from alkaline materials, strong
bases, strong acids, oxoacids, epoxides.
Waste Disposal
Because of the high value of
the metal, recovery is the economically indicated disposal
method.
