Laboratory Use
Aqueous ammonia is used in traditional qualitative inorganic analysis as a complexant and base. Like many amines, it gives a deep blue coloration with copper(II) solutions. Ammonia solution can dissolve silver residues, such as that formed from Tollens' reagent.
When ammonium hydroxide is mixed with dilute hydrogen peroxide in the presence of a metal ion, such as Cu2+, the peroxide will undergo rapid decomposition.

Famous quotes containing the word laboratory:
“Today, each artist must undertake to invent himself, a lifelong act of creation that constitutes the essential content of the artist’s work. The meaning of art in our time flows from this function of self-creation. Art is the laboratory for making new men.”
—Harold Rosenberg (1906–1978)
“For a novelist, a given historic situation is an anthropologic laboratory in which he explores his basic question: What is human existence?”
