Product Overview
Magnesium nitrate hexahydrate ARS, ACS is a high-purity chemical compound designed for demanding laboratory applications. This crystalline powder meets both Analytical Reagent Standard (ARS) and American Chemical Society (ACS) specifications, ensuring exceptional purity and consistency. With a minimum assay of 99%, it provides reliable results in quantitative analysis and synthesis protocols. The hexahydrate form offers excellent water solubility, making it suitable for preparing standard solutions and as a reagent in gravimetric analysis. Its stable nature under controlled conditions ensures long shelf life without degradation. The compound’s hygroscopic properties require proper storage to maintain purity, while its compatibility with most lab glassware and equipment makes it versatile for various experimental setups. This grade is particularly valued for its low impurity profile, with controlled levels of heavy metals and other contaminants that could interfere with sensitive analyses. The product’s consistent particle size distribution ensures uniform dissolution rates, which is critical for reproducible experimental outcomes.
FAQs
1. What is the difference between ARS and ACS grades in this magnesium nitrate?
ARS (Analytical Reagent Standard) and ACS (American Chemical Society) grades both indicate high purity, but ACS typically has stricter specifications for certain impurities. This product meets both standards, ensuring maximum reliability for critical applications.
2. Can this magnesium nitrate be used for preparing buffer solutions?
Yes, the high solubility and purity make it suitable for preparing buffer solutions where precise ionic concentrations are required, though you may need to adjust pH separately as magnesium nitrate itself doesn’t provide buffering capacity.
3. What storage conditions are recommended to prevent moisture absorption?
Store in a tightly sealed container with desiccant in a cool, dry place below 30°C. For long-term storage, consider vacuum sealing or using moisture-barrier bags to maintain the hexahydrate form.
4. Is this product compatible with plastic labware?
While generally compatible with most lab plastics, prolonged contact with strong solutions may affect some polymers. For critical applications, use glass or chemically resistant plastics like PTFE or PP.
5. What alternatives exist if I need anhydrous magnesium nitrate?
For anhydrous requirements, you would need to source magnesium nitrate specifically labeled as anhydrous or prepare it through controlled dehydration of this hexahydrate form under vacuum at elevated temperatures.
