Tollen’s reagent is used for the detection of aldehyde, when a solution of $A g N O_{3}$ is added to glucose with $N H_{4} O H$ then gluconic acid is formed.

$A g^{+} + e^{-} \to A g;$ $E_{r e d}^{\circ} = 0.8 V$

$C_{6} H_{12} O_{6} + H_{2} O \to C_{6} H_{12} O_{7}$ (Gluconic acid) $+ 2 H^{+} + 2 e; E_{o x d}^{\circ} = - 0.05 V$

$[A g (N H_{3})_{2}]^{+} + e^{-} \to A g (S) + 2 N H_{3}; E_{r e d}^{\circ} = - 0.337 V$
