Sulfuric acid, rhodium salt
Sulfuric acid, rhodium salt (CAS: 10489-46-0), commonly known as rhodium(III) sulfate, is a precious-metal compound serving as a water-soluble source of rhodium ions for catalytic, electroplating, and materials applications. In catalysis, it acts as a precursor for supported and homogeneous rhodium catalysts employed in hydrogenation, hydroformylation, and carbonylation reactions central to pharmaceutical and fine chemical synthesis. The electroplating industry utilizes rhodium sulfate solutions to deposit bright, hard, corrosion-resistant rhodium coatings on jewelry, electrical contacts, and reflector surfaces. It also serves as a precursor for rhodium oxide coatings on titanium anodes used in chlor-alkali electrolysis, and in the manufacture of rhodium-based thermocouples and catalysts. Given the high value of rhodium, material recovery and recycling are integral to its use. Consistent purity and rhodium content are essential for reliable performance in these high-value applications.
