... The position of equilibrium lies well over to the left-hand side (K < 1) and so, at equilibrium, there will be few ammonium and hydroxide ions compared with the much larger number of ammonia molecules. Therefore, because [OH-(aq)] > [H+(aq)], ammonia is basic, but is weak compared with sodium hydrox ...
