Molybdic Acid (CAS 7782-91-4), technical and reagent grade, supplied wholesale by Zyntex. Starting material for molybdates and catalysts, pigment raw material, micronutrient source and analytical reagent. CoA and SDS with every lot.
Molybdic acid is a hydrated form of molybdenum trioxide, often written as H2MoO4 or MoO3·H2O. It is a white to pale yellow crystalline powder that dissolves only slightly in water but readily in alkaline solutions and ammonia, where it forms molybdate salts.
Chemical producers use it as a starting material for ammonium and sodium molybdates and for molybdenum catalysts used in refining and in the oxidation of hydrocarbons. Pigment producers use it for molybdate orange and corrosion-inhibiting molybdate pigments. In agriculture, molybdates made from it supply molybdenum, an essential micronutrient for legumes and other crops.
Laboratories use molybdate reagents to determine phosphate and silicate, for example in the molybdenum blue method with Phosphoric acid standards. For other molybdenum compounds, see Molybdenum(VI) oxide, Molybdenum Disulfide and Lithium molybdate.

⚠️ Safety & Handling: May cause eye and respiratory irritation; molybdenum trioxide-type compounds are suspected of causing cancer by inhalation. Avoid dust formation and wear dust protection, gloves and eye protection. Store in tightly closed containers in a dry place, away from strong reducing agents. Always consult the Safety Data Sheet (SDS) for full classification and handling instructions.
What is the difference between molybdic acid and molybdenum trioxide?
Molybdic acid is a hydrated form of molybdenum trioxide. It dissolves more easily in alkaline solutions and is convenient for preparing molybdate salts.
