Rhodium(III) Sulfate Solution (CAS No. 10489-46-0) is a specialized chemical compound with critical applications in industries ranging from electroplating to catalysis. As a supplier of high-quality chemical intermediates, we understand that our clients, whether they are procurement managers or research scientists, need comprehensive information regarding product specifications and safe handling procedures. This article aims to provide a clear overview of Rhodium(III) Sulfate Solution.

Key Specifications and Properties

The chemical identity and physical properties of Rhodium(III) Sulfate Solution are fundamental to its effective use. Here are the key specifications:

  • Chemical Name: Rhodium(III) Sulfate Solution
  • CAS Number: 10489-46-0
  • EINECS Number: 234-014-5
  • Chemical Formula: Rh2(SO4)3
  • Molecular Weight: Approximately 494 g/mol (for the anhydrous form; hydrated forms will have higher molecular weights). Manufacturers often specify the rhodium content per liter.
  • Appearance: The solution is typically described as a brownish-red liquid. This visual characteristic is important for identifying the product.
  • Purity: Minimum purity levels commonly range from 97%, with specific rhodium concentrations available from 1 g/L up to 100 g/L, depending on the manufacturer's offering.
  • Solubility: It is miscible with water, ethanol, and mixtures of ethanol and water (e.g., 3:1 ethanol/water). This high solubility is crucial for its application in aqueous and semi-aqueous systems.
  • Density: Typically around 1.217 g/mL at 25℃ (lit.).
  • Melting Point/Boiling Point: As a solution, these are less relevant than the properties of the dissolved solute and solvent. The solute itself decomposes at temperatures above 500℃.

Primary Applications

The most prominent application for Rhodium(III) Sulfate Solution is in rhodanizing, a specialized surface treatment process. It also serves as a critical component in precious metal electroplating, providing durable, bright, and corrosion-resistant finishes. Furthermore, it is utilized as a precursor in the synthesis of rhodium-based catalysts for various chemical reactions.

Safe Handling and Storage Guidelines

As with many chemical compounds, especially those involving precious metals and acidic components (sulfuric acid is often present), safe handling and storage are paramount. While specific Safety Data Sheets (SDS) should always be consulted, general precautions include:

  • Personal Protective Equipment (PPE): Always wear appropriate PPE, including chemical-resistant gloves (e.g., nitrile or neoprene), safety goggles or a face shield, and protective clothing.
  • Ventilation: Ensure adequate ventilation in the work area to prevent inhalation of any vapors or mists. Work in a well-ventilated fume hood if possible.
  • Skin and Eye Contact: Rhodium compounds and the acidic nature of the solution can cause irritation or burns. In case of skin contact, wash immediately with soap and plenty of water. For eye contact, rinse cautiously with water for several minutes, removing contact lenses if present and easy to do. Seek immediate medical attention if irritation persists or is severe.
  • Ingestion: Do not ingest. If swallowed, rinse mouth and do NOT induce vomiting. Seek immediate medical attention.
  • Storage Conditions: Store in a cool, dry, well-ventilated area in tightly sealed containers. Keep away from incompatible materials such as strong bases, oxidizing agents, and reducing agents.
  • Disposal: Dispose of waste material in accordance with local, regional, and national regulations. Consult with an environmental specialist or regulatory body for proper disposal procedures.
