FAQs
1. What is the solubility of sodium acetate trihydrate in water at room temperature?
Sodium acetate trihydrate exhibits high solubility in water, with approximately 365 g/L dissolving at 20°C, forming a clear, colorless solution suitable for buffer preparation.
2. Can this reagent be used for DNA extraction protocols?
While primarily employed as a buffering agent, its high purity makes it compatible with certain DNA extraction workflows where acetate-based precipitation steps are required, though protocol-specific validation is recommended.
3. How does this compare to anhydrous sodium acetate in terms of molar concentration?
The trihydrate form contains three water molecules per sodium acetate unit, resulting in a lower molar concentration (82.03 g/mol for trihydrate vs. 82.03 g/mol for anhydrous when adjusted for water content) when preparing solutions.
4. What storage conditions are ideal to prevent caking or degradation?
Store in a tightly sealed container at room temperature (15–25°C) with desiccant packs to minimize humidity exposure, as excessive moisture can lead to clumping without affecting chemical purity.
5. Is this product compatible with HPLC or GC analysis?
Its 99.5% purity and low UV absorbance make it suitable for HPLC mobile phase preparation, though filtration (0.22 µm) is advised prior to use to remove potential particulate matter that could affect column performance.
