Ammonium Molybdate
Ammonium Molybdate (Product Code: SCL367/085) is an analytical reagent in a 100 gm pack, used to detect phosphate in biology and chemistry practicals, where it forms a distinctive yellow precipitate. Teachers use it to show that bone ash, plant ash, soil or fertiliser samples contain phosphorus, and an MSDS is supplied with every pack. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, a laboratory chemicals supplier in India for teaching and institutional labs.

What Is the Ammonium Molybdate Used For?
The classic teaching use is the phosphate test. The sample is dissolved or extracted in dilute nitric acid, a solution of ammonium molybdate is added and the tube is warmed gently; a canary-yellow precipitate of ammonium phosphomolybdate confirms phosphate. Students meet this test when studying the mineral content of bone, the phosphorus held in plant tissue, or the composition of soil and fertiliser samples in school and college practical sessions.
For reliable results, make up the reagent solution in distilled water shortly before the class and use thoroughly rinsed glassware — traces of phosphate-containing detergent left in a tube can give a false positive. Keep the container tightly closed in a cool, dry place, read the supplied MSDS before handling, and have students wear gloves and eye protection whenever acids are involved.

Items a lab typically needs to run the phosphate test with this reagent:
- Nitric Acid (Conc) — provides the acidic conditions the phosphomolybdate reaction needs.
- Test Tubes (With Rim) — reaction vessels for sample and reagent.
- Spirit Lamp — gentle warming to develop the yellow precipitate.
- Digital Analytical Balance — weighing the reagent when preparing a solution.
- Distilled Water — dissolving the reagent and final rinsing of glassware.

Frequently Asked Questions
What quantity of Ammonium Molybdate is in one pack?
Each pack contains 100 gm of Ammonium Molybdate, listed as an analytical reagent. For larger requirements, several packs can be quoted together; contact us to discuss the total quantity your laboratory needs.
What result does Ammonium Molybdate give in the phosphate test?
In the phosphate test, Ammonium Molybdate added to an acidified sample and warmed gently gives a canary-yellow precipitate of ammonium phosphomolybdate. No yellow precipitate indicates that phosphate was not detected in the sample.
Why can glassware cause a false positive with Ammonium Molybdate?
Traces of phosphate-containing detergent left in a test tube react with Ammonium Molybdate just like a real sample would. Rinse all glassware thoroughly with distilled water before the test to avoid a misleading yellow result.
Is a safety data sheet supplied with Ammonium Molybdate?
Yes. Ammonium Molybdate is supplied with an MSDS setting out hazards, storage and first-aid guidance. Keep it with your laboratory safety records, and ensure students wear gloves and eye protection whenever acids are used.
What is the shelf life of Ammonium Molybdate?
The shelf life of Ammonium Molybdate depends on the chemical, its grade and storage conditions, so no fixed period is quoted. Ask us for the expiry date of the batch you are quoted, and keep the container sealed, cool and dry.
Is a certificate of analysis included with Ammonium Molybdate?
Only the MSDS is listed as supplied with Ammonium Molybdate. If your institution needs further batch documentation such as an analysis report, raise the requirement through our contact page before ordering and we will confirm what is available.
Who supplies Ammonium Molybdate in bulk?
Ammonium Molybdate is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, to schools, colleges and distributors across India and international markets. Share code SCL367/085, the quantity and the delivery location for a quotation.
