Ammonium chloroplatinate

Chemical properties

YELLOW CUBIC CRYSTALS

Chemical properties

Ammonium chloroplatinate is an orange-red crystalline cubic solid or yellow powder which decomposes when heated.

The Uses of Ammonium chloroplatinate

Platinum plating; manufacture of spongy platinum.

The Uses of Ammonium chloroplatinate

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.
