At this point the mixture will be clear, and there are now aqueous silver ions existing as (Ag (NH 3) 2) + complexes in the mixture, which is the main component of Tollens' reagent.
At this point the mixture will be clear, and the silver will be back in its aqueous ionic form again, as Ag + (aq). The ammonia then co-ordinates to the Ag + ions to form the (Ag (NH 3) 2) + complex, which is the main component of Tollens' reagent.
