    1. The oxidation state of Ag+ is the same, and there will be some similar properties, but they are not the same thing. Ag(NH3)2+ is much better at forming complexes with alkenes, for example.

    1. Sure you can use any other mild or strong oxidising agents like Fehling Solution, HNO3,acidic/basic KMnO4/K2Cr2O7 and many more..
