Tollen's reagent is a mixture of liquid ammonia and silver nitrate , It was named after its discoverer, the German chemist
Berhard Tollens.
Basically positive test means Tollens' reagent oxidize, aldehyde aromatic
aldehyde and alpha-hydroxy ketone functional groups
into corresponding acid and the precipitation of elemental silver, often producing a characteristic "silver mirror" on the inner surface of the reaction vessel.
AgNO3 + NH4OH
--> NH4NO3 +AgOH
