Question

How do acids and bases react with each other ?

Answer 1

acids and bases react with each other to produce salt and water and the reaction is called neutralization reaction

Answer 2

Acids and bases can combine in other ways, however, and when they do, the product isn't always a salt. For example, when you add zinc to ammonia, the reaction results in a complex ion. Until the introduction of the Lewis theory of acids and bases, this wouldn't even have been considered an acid/base reaction.
