So let's examine the following example. Hydrochloric acid, a strong acid reacts with ammonia, a weak base, and in the presence of water, that they associate into H plus ion, a chloride ion. And our ammonia. Now ammonia reacts with H to create Ammonium, a positively charged ion. Now this positively charged ion then reacts with the chloride to neutralize the charge, creating an acidic salt. Now, since we begin with water, we also have water at the end result.
