Liquid ammonia (anhydrous NH3(l)) is often used as a solvent. Like water, ammonia undergoes autoionization by the transfer of a proton: 2NH3 NH4+<-----> + NH2-, K = 1×10^-33 at -50°C 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 ammonia at -50°C.? part(b)Calculate [NH4+] (mol/L) in a 3.93×10-10 M solution of acetic acid in liquid ammonia at -50°C? part (c) Estimate [NH2-] (mol/L) in a 3.93×10-10 M solution of acetic acid in liquid ammonia at -50°C
