Ammonia water is an aqueous solution of gaseous ammonia, mainly composed of NH3 · H2O, which is monohydrate ammonia. It is colorless, transparent, and has a pungent odor. Ammonia water has a lower density than water, is unstable, volatile, and easily decomposes when exposed to light and heat. Concentrated ammonia water usually contains 28% -29% ammonia
