Sodium Molybdate Dihydrate CAS#10102-40-6
High Solubility: Easily dissolves in water (39 g/100 mL at 25℃), making it suitable for various applications.
Stable at Room Temperature: Maintains stability under normal conditions, ensuring reliable performance.
Mildly Alkaline: Aqueous solutions have a pH of 9-10, making it effective in specific chemical reactions.
Heat Sensitivity: Loses crystalline water when heated above 100℃, transitioning into anhydrous sodium molybdate for diverse industrial uses.
A white crystalline powder or colorless crystal, readily soluble in water (approximately 39 g/100 mL at 25℃). Its aqueous solution is mildly alkaline with a pH around 9 to 10. It remains stable at room temperature but loses crystalline water when heated above 100℃, forming anhydrous sodium molybdate (Na₂MoO₄, CAS#7631-95-0). When reacting with strong acids, it produces a precipitate of molybdic acid (H₂MoO₄).
