Ammonia is a base and H2SO4 is an acid. So neutralisation reaction happens and salt will be formed. 2 NH3 + H2SO4 = (NH4)2SO4. read more
Ammonia is a base. Sulfuric acid is, well, as the name suggests, an acid. Acids react with bases to form their corresponding salts and water. Ammonia reacts with sulfuric acid to produce ammonium sulfate and water. read more
If you really want to write the reaction for sulfuric acid and "ammonium hydroxide", then it would look like this: NH3(aq) + H2SO4(aq) --> (NH4)2SO4(aq) And it would be **even better** to write it as the ionic equation, since some of these species only exist as ions in solution. read more
