... Abstract. Ammonia doesn't just dissolve in water; it reacts with it. When you mix these two clear solutions together, they react to form a new compound. Removing a positively-charge proton from water leaves it negatively-charged, so add a negative sign to the hydroxide particle ("OH-"). In this case, the water molecule acts as an acid and adds a proton to the base.
