Product Overview
Sodium molybdate dihydrate in ARS and ACS grades is a highly purified crystalline powder designed for precision in laboratory settings. This reagent is characterized by its exceptional solubility in water, forming clear solutions that are critical for various chemical analyses. The ARS (Analytical Reagent Standard) and ACS (American Chemical Society) certifications ensure minimal impurities, making it suitable for demanding applications where accuracy is paramount. The dihydrate form provides stability, allowing for consistent performance across repeated experiments. Its role as a source of molybdate ions is essential in spectrophotometric determinations, particularly in phosphate and silicate analysis. The compound’s non-hygroscopic nature further enhances its shelf life and ease of handling. Whether used in volumetric titrations or as a component in buffer solutions, this sodium molybdate variant delivers reliable results. The 250 g pack size offers an optimal balance between quantity and convenience, catering to both small-scale and bulk requirements in research environments.
FAQs
1. What is the solubility of sodium molybdate dihydrate in water?
Sodium molybdate dihydrate is highly soluble in water, typically dissolving at approximately 84 g per 100 mL at 20°C, forming a clear, colorless solution.
2. Can this product be used for spectrophotometric analysis?
Yes, the ARS/ACS grade ensures low impurity levels, making it suitable for spectrophotometric applications, particularly in phosphate and silicate determinations.
3. How should this reagent be stored for long-term stability?
Store in a tightly sealed container at room temperature, away from moisture and incompatible substances, to maintain its stability and purity.
4. Is this sodium molybdate compatible with acidic solutions?
It is stable in neutral to slightly alkaline conditions but may decompose or form precipitates in strongly acidic environments.
5. What alternatives exist for molybdate-based reagents?
Ammonium molybdate is a common alternative, though sodium molybdate is often preferred for its higher solubility and stability in solution.
