Acids & Bases

Ammonia solution (05003)

26% NH3, extra pure, meets analytical specification of Ph. Eur., assay 25.0 - 30.0%

Overview
Ammonia is a compound of nitrogen and hydrogen with the formula NH3 and is a colorless gas with a characteristic pungent smell. Although common in nature and in wide use, ammonia is both caustic and hazardous in its concentrated form. Ammonia is also a building block for the synthesis of many pharmaceutical products and is used in many commercial cleaning products.
