Rhodium(III) sulfate Usage And Synthesis

Description

When heated to decomposition, this product can emit acid mists and toxic gases (including oxides of sulphur and rhodium compounds). This product is not compatible with bases, halides, water, cyclopentadiene, cyclopentanone, oxime, nitroaryl amines, haxalithium disilicide, phosphorus (III) oxide, chlorine bromine pentafluoride, trifluoride, and oxygen difluoride (OF2). Avoid contact with metals. This product can react with water to generate heat.

Description

Attempts to prepare Rhodium(III) sulfate from rhodium hydroxide and sulfuric acid lead to two different products, depending on the conditions. these are yellow rhodium sulfate Rh2(SO4)3 ? 15 H2O and red rhodium sulfate Rh2(SO4 )3? 4H2O.

Chemical Properties

reddish yellow solid; ~8% aqueous solution [ALD94] [KIR82]

Uses

Rhodium(III) sulfate is used as plating reagents and additives for noble metal. It is also used for fancy plating rhodium in jewellery and horologe. Further, it is used for decorative applications.

General Description

Rhodium(III) sulfate is an anhydrous metal sulfate that is formed by oxidizing rhodium with concentrated sulphuric acid. It is a red crystal that forms a hydrated solution at high temperatures. It is majorly used in the production of high performance coatings by electroplating technique.
