About silver ammonia solution

There is ionization balance between ammonium ion and hydroxide ion in the solution. In the second reaction, there is ammonia monohydrate in the reactant, which hinders the formation of ammonia monohydrate in other ways and ensures the silver hydroxide in the product.

It can be said that the silver ammonia reaction plays a role in silver diammonium, which has nothing to do with anions, but this reaction is generally not considered because nitric acid is oxidizing in acidic solution.
