Frequently Asked Questions About Ammonium Molybdate

What is Ammonium Molybdate used for in laboratories?

Ammonium Molybdate is used in inorganic chemistry experiments, phosphate detection, quantitative phosphate analysis, and the preparation of molybdate-containing reagents. It also supports research involving molybdenum chemistry. The exact application depends on the analytical method, chemical form, and required reagent specifications.

What is the molecular formula of Ammonium Molybdate Tetrahydrate?

The molecular formula is (NH₄)₆Mo₇O₂₄·4H₂O, and its formula mass is approximately 1235.93 g/mol. The formula includes four water molecules of crystallization. The anhydrous form has a different molecular composition, formula mass, and CAS number, so the chemical form should be confirmed when ordering.

What is the CAS number of Ammonium Molybdate Tetrahydrate?

The CAS Registry Number for Ammonium Molybdate Tetrahydrate is 12054-85-2. It is also known as ammonium heptamolybdate tetrahydrate or ammonium paramolybdate tetrahydrate. This identifier helps distinguish the tetrahydrate from anhydrous ammonium molybdate and other molybdenum-containing compounds.

How is Ammonium Molybdate used in phosphate analysis?

In suitable analytical procedures, ammonium molybdate reacts with phosphate under controlled acidic conditions to form molybdate-containing products. Depending on the method, these products can generate a measurable colour response or another analytical signal. Reagent concentrations, reaction conditions, and measurement procedures must follow the validated analytical method.

How should Ammonium Molybdate be stored and handled?

Keep Ammonium Molybdate in a tightly closed container in a cool, dry location and protect it from contamination. Avoid inhaling dust and wear suitable gloves, protective clothing, and safety goggles. Consult the current Safety Data Sheet for the substance-specific hazards, handling precautions, and waste-disposal requirements.

Storage Conditions for Ammonium Molybdate

Store Ammonium Molybdate Tetrahydrate in a tightly closed, compatible container in a cool, dry, well-ventilated area at the recommended ambient temperature.
