It is surprising what the amateur chemist can do with a fifteen-cent bottle of ordinary household ammonia.

Being a mixture of ammonia dissolved in water, this pungent-smelling liquid offers an ever-ready supply of ammonia gas for the home laboratory. Even at room temperature, the gas is released from the liquid. By heating it, the experimenter can obtain the gas in larger quantities.

Strictly speaking, household ammonia is not ammonia at all, but ammonia water or ammonium hydroxide. Although ammonia can be liquefied, it is a colorless gas at normal temperatures. The fact that it dissolves readily in water makes the manufacture of ammonia water possible.
