Textbook Problem J9

[KDeguzman_Dis3K]

"Identify the salt that is produced from the acid–base neutralization reaction between (a) potassium hydroxide and acetic acid,
(b) ammonia and phosphoric acid; (c) calcium hydroxide and bromous acid; (d) sodium hydroxide and hydrosulfuric acid,
(both atoms react). Write the complete ionic equation for each reaction."

For b, ammonia and phosphoric acid, where is the H2o in the equation? In the answer key, 3 NH4 and PO4 is produced. In all neutralization reactions, I thought salt and water was produced.

[Rhea Jain 2I]

The reason that water is not formed in this reaction is because water is only formed in a neutralization reaction when a strong base is present. If the base is not strong, then water will not be created.
