Product Overview
Cerium(III) sulfate octahydrate from REacton™ delivers ultra-high purity at 99.999% metals basis, making it an essential reagent for demanding laboratory applications. This crystalline powder exhibits exceptional solubility in water, forming clear solutions that maintain stability across a wide pH range. The octahydrate form ensures consistent stoichiometry in reactions, while the rigorous purification process eliminates trace metal contaminants that could interfere with sensitive analyses. Its rare earth composition provides unique catalytic properties, particularly in oxidation-reduction systems where cerium’s variable oxidation states are leveraged. The material’s low moisture content (<0.5%) and tightly controlled particle size distribution (90% <100μm) guarantee reproducible results in quantitative applications. Packaged under inert atmosphere to prevent oxidation, this grade meets ASTM C1199-11 standards for high-purity cerium compounds. The REacton™ certification verifies batch-to-batch consistency through ICP-MS analysis, with maximum impurities limited to 10ppm for any individual element. Ideal for applications requiring precise cerium ion concentrations, this product maintains its specifications for 24 months when stored as directed.
FAQs
1. What is the typical solubility of this cerium(III) sulfate octahydrate in water at room temperature?
It exhibits solubility of approximately 28g/100mL in water at 20°C, forming a slightly acidic solution with pH around 4.5-5.0 when fully dissolved.
2. Can this product be used directly in electrochemical applications without further purification?
The 99.999% metals basis purity makes it suitable for most electrochemical applications, though some researchers perform an additional recrystallization step when working with particularly sensitive systems like solid oxide fuel cells.
3. What’s the difference between this REacton™ grade and standard laboratory grades?
REacton™ grade undergoes three additional purification steps including zone refining and electrodialysis, reducing total impurities from typical 99.9% grades by two orders of magnitude, particularly for transition metals like iron and copper.
4. How should this be stored to maintain the 99.999% purity specification?
Store in the original container with desiccant packs at 15-25°C, protected from light and moisture. Once opened, reseal immediately and use within 6 months for optimal purity retention.
5. What analytical techniques are used to verify the 99.999% purity claim?
The certification employs ICP-OES for bulk analysis, ICP-MS for trace elements, and XRF for non-metallic impurities, with each batch accompanied by a certificate of analysis detailing all 67 tested elements.
