Tollen's reagent is ammoniacal silver nitrate solution. It is prepared as follows

A g N O_{3} + (excess) N H_{4} O H ⟶ Tollen’s reagent [A g (N H_{3})_{2}] O H + H_{2} O

Tollen's reagent is a mild oxidising agent and oxidise only aldehydes to form silver mirror. It is used to differentiate between aldehydes and ketones

RC H O + 2 [A g (N H_{3})_{2}] O H ⟶

RCOON H_{4} + Silver mirror 2 A g ↓ + 3 N H_{3} + H_{2} O
