Ammonium Hydroxide (Ammonia)
Ammonium Hydroxide (Ammonia) (Product Code: SCI-529/229) is an analytical reagent grade solution of ammonia in water used as a weak alkali in qualitative analysis, complex-ion tests and gas diffusion demonstrations in school and college laboratories. It is supplied in a 500 ml bottle with an MSDS; the strength is not stated in the listing and is confirmed on enquiry. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India.

What Is Ammonium Hydroxide Used For?
In cation analysis, ammonium hydroxide precipitates metal hydroxides such as gelatinous white aluminium hydroxide and red-brown iron(III) hydroxide, while in excess it turns copper(II) solutions a deep blue as the copper-ammine complex forms. It also dissolves silver chloride, which separates it from silver bromide and iodide, and it is needed to prepare Tollens’ reagent. Few bottles on a salt analysis bench in a school or college are opened as often.
A favourite demonstration places cotton wool soaked in ammonia solution at one end of a long glass tube and cotton wool with concentrated hydrochloric acid at the other. A white ring of ammonium chloride forms nearer the acid end, showing that the lighter ammonia molecules diffuse faster. The liquid gives off pungent, irritating vapour, so open it in a fume cupboard, keep the cap tight and store it cool. Never mix it with bleach, which releases toxic chloramine gases.
Supplier
Ammonium Hydroxide (Ammonia) is supplied by Jain Scientific Equipments Private Limited, which trades as ScienceLab from Ambala, Haryana, and provides the reagents used in inorganic salt analysis. The acids, salts and glassware needed for the same bench can be included in a single quotation. See the ScienceLab profile page.
Related Laboratory Equipment
Tests and demonstrations with Ammonium Hydroxide (Ammonia) often use:
- Hydrochloric Acid — meets ammonia vapour in the diffusion-tube demonstration.
- Hydrated Copper Sulfate — turns deep blue when excess ammonia solution is added.
- Silver Nitrate — combined with ammonia solution to prepare Tollens’ reagent.
- Ammonium Chloride 200 g — used with ammonia solution when precipitating group hydroxides in cation analysis.
- Fume Cupboard, Ductless — keeps pungent vapour away from students.

Frequently Asked Questions
Is Ammonium Hydroxide the same as ammonia solution?
Yes. Ammonium Hydroxide (Ammonia) is ammonia gas dissolved in water, also sold as ammonia water or aqueous ammonia. Listing SCI-529/229 is analytical reagent grade in a 500 ml bottle with MSDS; ask us to confirm its concentration before ordering.
Which laboratory tests use Ammonium Hydroxide (Ammonia)?
Ammonium Hydroxide (Ammonia) is used to precipitate metal hydroxides in cation analysis, to form the deep blue copper-ammine complex, to dissolve silver chloride and to prepare Tollens’ reagent. It also features in the ammonia and hydrogen chloride diffusion demonstration.
What safety precautions does ammonia solution need?
Ammonium Hydroxide (Ammonia) releases pungent vapour that irritates the eyes, nose and lungs, and the liquid can burn skin. Open it in a fume cupboard, wear goggles and gloves, keep it cool and tightly closed, and never mix it with bleach or other hypochlorite solutions.
What is the shelf life of Ammonium Hydroxide (Ammonia)?
Shelf life depends on the chemical, its grade and storage conditions, and ammonia solution also loses strength if the cap is left loose. Ask us for the expiry date of the Ammonium Hydroxide (Ammonia) batch you are quoted, and keep the bottle sealed in a cool place.
Can Ammonium Hydroxide (Ammonia) be shipped in quantity?
Ammonium Hydroxide (Ammonia) can be quoted in multiples of the 500 ml bottle for schools, colleges and dealers in India and international markets. As a corrosive liquid it has transport rules, so give Jain Scientific Equipments Pvt Ltd (ScienceLab) the destination when you enquire.
