Ammonia is a weak base because it produces ammonium and
hydroxide ions. Weak bases are so called weak because in the solution, these bases
do not fully convert itself into hydroxide ions or in other words, it does not
fully ionize in the solution.
ammonia is a weak base ( electrolyte) because ammonia reacts with water to produce ammonium and hydroxide ions. When hydroxide ion reacts with ammonium, it results to water and ammonia. it only proves that ammonia is rather a base because of its acceptance of hydrogen ion from water.
