About This Product
In qualitative analysis, ammonium hydroxide is added slowly to test solutions to produce precipitates that help identify metal ions. The bottle is opened carefully in a ventilated area or fume hood, with gloves, goggles and a lab coat, and only the quantity needed is measured out. It is kept apart from acids, oxidisers and unknown reagents unless the approved procedure allows mixing. The Ammonium Hydroxide Chemical Solution is available for supply within India and for export to Uzbekistan, Serbia, Republic of the Congo, Qatar and Senegal.
Frequently Asked Questions
Q1. Why is ventilation needed when using ammonium hydroxide?
The solution releases irritating ammonia vapour, so it is handled in a ventilated area or fume hood and the vapour is not inhaled.
