I thought Ag+ aren't soluble. How do compound's solubility in NH3 differ from in water?

In this case, it can form a complex ion (AgNH4+), which is soluble because of its charged nature.

transition metals tend to form complex ions with ammonia and H20 due to their loose valence shell rules and the accessible lone pairs on ammonia and H20
