Answer 2

   Ammonia is easily dissolvable in Water forming Hydroxide. Ammonia in air dissolves in humidity in air. Also Ammonia could dissolve quickly in the humid mucus in the nose.

   In our nose we have chemoreceptors. They identify Ammonia faster due to this reason.  Further the strong reactivity of Ammonia with our smell receptors causes us to feel that it is pungent.  Our smell receptors can identify rotten smells and Ammonia more quickly and better than other smells.  So that keeps us away from toxic gases.

    Which gas or smells which way is decided by its reaction with the smell receptors in our olfactory (smelling sensor) system.
