Basic Information

Sodium Molybdate Dihydrate
White crystalline powder; Colorless crystals

Sodium molybdate dihydrate is a water-soluble crystalline material supplied as white powder or colorless crystals. It forms mildly alkaline solutions and loses its water of crystallization on heating. Typical uses include corrosion control in circulating water, metal phosphating, catalyst preparation, semiconductor film manufacture, and colorimetric analysis of metal ions.

product description

High Water Solubility:White crystalline powder or colorless crystals dissolve effectively in water, with a solubility of about 39 g/100 mL at 25°C.


Mild Alkalinity:The aqueous solution is weakly alkaline, with a pH of approximately 9–10, suitable for various chemical applications.


Thermal Stability:Stable at room temperature, retaining its crystalline structure under normal conditions.


Chemical Reactivity:Reacts with strong acids to form molybdic acid (H₂MoO₄) and can transform into anhydrous sodium molybdate (Na₂MoO₄) upon heating above 100°C, enabling diverse industrial and chemical uses.

Product Description of Sodium Molybdate Dihydrate CAS#10102-40-6

Sodium Molybdate Dihydrate is a white crystalline powder or colorless crystal, highly soluble in water with solubility of about 39 g/100 mL at 25°C. Its aqueous solution is weakly alkaline with pH ranging from 9 to 10. It remains stable at room temperature. When heated above 100°C, it gradually loses crystal water to form anhydrous sodium molybdate (Na₂MoO₄, CAS 7631-95-0). It reacts with strong acids to generate molybdic acid (H₂MoO₄) precipitate.


Product Application of Sodium Molybdate Dihydrate CAS#10102-40-6

Sodium Molybdate Dihydrate (CAS 10102-40-6) has broad application prospects. Industrially, it is used as a circulating water corrosion inhibitor, metal phosphating agent and chemical catalyst. In the pharmaceutical field, it acts as a chemical intermediate and a reagent for enzyme research. In the electronics industry, it is applied to the preparation of semiconductor films and other components. In analytical chemistry, it serves as a chromogenic agent for the detection of heavy metal ions. For storage and handling, it should be kept in a sealed container and kept away from strong acids, with relevant protective measures properly taken.
