Rhodium oxide Chemical Properties,Uses,Production
Chemical Properties
Rhodium oxide is YELLOW POWDER
Physical properties
Gray crystalline solid or amorphous powder; corundum-type structure; density 8.20 g/cm3; decomposes at about 1,100 to 1,150°C; insoluble in water, acids, or aqua regia.
The pentahydrate Rh2O3?5H2O is a yellow precipitate; soluble in acids; partially dissolves in hot water; ignites to form anhydrous oxide.
The trihydrate Rh2O3?3H2O is a black precipitate; insoluble in acids.
Uses
RH2o3 is used to make rhodium metal and its various salts. Also, the oxide is a catalyst for hydrogenation.
Production Methods
Rhodium(III) oxide, Rh2O3, can be prepared by heating the finely divided metal or its nitrate in air or O2. The rhodium(IV) oxide is also known. Rhodium trihydroxide may be precipitated as a yellow compound by adding the stoichiometric amount of KOH to a solution of RhCl3. The hydroxide is soluble in acids and excess base. When the freshly precipitated Rh(OH)3 is dissolved in HCl at a controlled pH, a yellow solution is first obtained in which the aquochloro complex of Rh behaves as a cation.
