What is the lewis structure for HIO3, including lone pairs. Assign formal charges. If a more equally stable resonance exists, draw it(them).
Since ammonia is better proton acceptor than water, the ionization of acids is relatively enhanced in liquid ammonia. For example, acetic acid is a strong acid in liquid ammonia. part( a)Estimate [NH4+] (mol/L) in pure (i.e. neutral) liquid ammoni..
