Ammonia is remarkable for its strong affinity for water, and is consequently readily absorbed by it. This solution is called aqua ammonia, and is the form in which it is most commonly sold and used. By union with acids, like other alkalies, it forms salts, and thus loses the pungent odor peculiar to Fig. 16. this gas. When ammonia is combined with aromatics, it forms the smelling salts of the shops. Ammonia is one of the most active elements of farm- yard manure ; but, without great care, large quantities of this valuable fertilizer are lost from the farm-yard, and carried off in the atmosphere. That ammonia has a strong affinity for acids may be shown by bringing a glass rod, which has been dipped in chlorohydric acid, over a vessel containing ammonia, when a dense white cloud is seen to rise, which is chloride of am- monium. (See Fig. 17.). Fig. 1^ Is it heavier or lighter than the atmosphere? How proved? For what is ammonia remarkable? In what form is it most commonly used ? Does it form salts with acids? Does it thus lose its pungent odor? Is it an active element of manure? Why is it readily lost from manure ? How proved that it has a strong affinity for acids ?.
