Adams' catalyst, also known as platinum dioxide, is usually represented as platinum(IV) oxide hydrate, PtO 2 •H 2 O. It is a catalyst for hydrogenation and hydrogenolysis in organic synthesis . [ 1 ]
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 ...
Cerium(III) nitrate – Ce(NO 3) 3; Cerium(III) oxide – Ce 2 O 3; Cerium(III) sulfate – Ce 2 (SO 4) 3; Cerium(III) sulfide – Ce 2 S 3; Cerium(IV) hydroxide – Ce(OH) 4; Cerium(IV) nitrate – Ce(NO 3) 4; Cerium(IV) oxide – CeO 2; Cerium(IV) sulfate – Ce(SO 4) 2; Cerium(III,IV) oxide – Ce 3 O 4; Ceric ammonium nitrate – (NH 4) 2 ...
An aqueous solution of rhodium chloride, chloroplatinic acid, and sodium nitrate is evaporated and then fused in a porcelain dish between 460-480°C until the oxides of nitrogen cease (≈10 minutes).
Sodium hexachloroplatinate(IV), the sodium salt of chloroplatinic acid, is an inorganic compound with the formula Na 2 [PtCl 6], consisting of the sodium cation and the hexachloroplatinate anion. As explained by Cox and Peters, anhydrous sodium hexachloroplatinate, which is yellow, tends to form the orange hexahydrate upon storage in humid air.
