Product Code : SCL-LC-12296
Ammonium Hydroxide (SKU SCL-LC-12296), also sold as ammonia solution or aqueous ammonia, is a weak alkali reagent for supervised chemistry work: salt analysis, ammonium-ion and metal-ion tests, pH adjustment and lessons on weak bases. It is meant for colleges and school laboratories where trained staff control dispensing and ventilation. Science Lab Supplies provides it from Ambala, India to schools, colleges, training institutes, tender contractors and distributors.
Specifications
The reagent is commonly written NH4OH, although it is really ammonia dissolved in water. It is a corrosive, volatile liquid: ammonia vapour escapes from the solution and pressure can build in a warm bottle. Concentration, grade, bottle size and pack size are not fixed here and are stated on the label and quotation.

Applications and Experiments for Ammonium Hydroxide
In qualitative analysis, ammonium hydroxide is added, often with ammonium chloride, to precipitate metal hydroxides and separate cations into groups. It also serves as the standard example of a weak base in pH lessons, and dilute solutions are used to adjust pH in prepared reagents under a written procedure.
- Class 11–12 chemistry: group reagent in systematic salt analysis for cations.
- Class 10 science: weak and strong bases and their pH.
- B.Sc. inorganic chemistry: semi-micro qualitative analysis of mixtures.
- Laboratory safety training: ventilation and handling volatile corrosive liquids.
Standard Scope of Supply
One container of ammonium hydroxide is supplied in the pack size quoted, labelled with batch, concentration and hazard details and sent with the Safety Data Sheet and transport documents. Shelf life depends on the chemical, its grade and storage conditions; ask us for the expiry date of the batch you are quoted.
Packing, MOQ and Lead Time
You may request one bottle or enough for a full year of salt-analysis classes; the quotation then gives the packing, delivery time and price for that quantity. Ammonium salts and other reagents from our laboratory chemicals range can be added to the same request.
As a registered exporter with an Importer-Exporter Code, Science Lab Supplies can ship to buyers in Egypt, Iraq, Nigeria, Kenya, Ghana and Ethiopia. Science Lab Supplies is registered for GST (GSTIN 06ADEPJ0574F2ZU). Enquiries can go through the contact page or the enquiry cart, and the lab tender page explains tender supply.
Frequently Asked Questions
Is ammonium hydroxide hazardous?
Yes. It is corrosive and irritating, and ammonia vapour escapes from the solution. Use it in a fume hood or well-ventilated room with gloves and eye or face protection, keep it away from acids, and never issue it for unsupervised student use.
What concentration is supplied?
The concentration is not fixed on this page. The percentage strength, grade and bottle size of the batch offered are stated on the label and confirmed in the quotation before you order.
Who supplies the Ammonium Hydroxide?
It is supplied from Ambala, India by Science Lab Supplies, which serves schools, colleges and distributors; the quotation names the concentration, grade and pack size.
How should the bottle be stored?
Keep it tightly closed in a cool, well-ventilated chemical store with secondary containment, apart from acids, strong oxidisers and heavy metal salts. Open it slowly, because vapour pressure can build up inside.
