Tollens' reagent is a chemical reagent most commonly used to determine whether a known carbonyl-containing compound is an aldehyde or a ketone. It is usually ammoniacal silver nitrate, but can also be other mixtures, as long as aqueous diamminesilver(I) complex is present.
[Ag(NH3)2]+ (aq) + e− → Ag (s) + 2 NH3 (aq)
RCHO (aq) + 3 OH− → RCOO− + 2 H2O + 2 e−
[Ag(NH3)2]+ (aq) + e− → Ag (s) + 2 NH3 (aq)
RCHO (aq) + 3 OH− → RCOO− + 2 H2O + 2 e−
