Paragraph:Tollen's reagent is used for the detection of aldehyde when a solution of ${\mathrm{AgNO}}_3$ is added to glucose with ${\mathrm{NH}}_4\mathrm{OH}$ then gluconic acid is formed $\begin{array}{rr}{\mathrm{Ag}}^{+}+e^{-}\to \mathrm{Ag}& E_{\text{red }}^{\circ }=0.8\mathrm{V}\\ {\mathrm{C}}_6{\mathrm{H}}_{12}{\mathrm{O}}_6+{\mathrm{H}}_2\mathrm{O}\to \text{ Gluconic acid }\left({\mathrm{C}}_6{\mathrm{H}}_{12}{\mathrm{O}}_7\right)+2{\mathrm{H}}^{+}+2e^{-};& -E_{\mathrm{red}}^{\circ }=-0.05\mathrm{V}\\ \mathrm{Ag}{\left({\mathrm{NH}}_3\right)}_2^{+}+e^{-}\to \mathrm{Ag}(s)+2{\mathrm{NH}}_3;& E_{\mathrm{red}}^{\circ }=0.337\mathrm{V}\end{array}$ [Use $2.303\times \frac{RT}{F}=0.0592$ and $\frac{F}{RT}=38.92$ at $298\mathrm{K}$ ]
