Tollens' reagent is used for the detection of aldehydes. When glucose and NH₄OH are added to a solution of AgNO₃ gluconic acid is formed. Use the following data to answer the questions.
Ag⁺ + e⁻ → Ag , E₁^° = 0.80 V;
C₆H₁₂O₆ + H₂O → C₆H₁₂O₇ + 2H⁺ + 2e⁻ , E₂^° = − 0.05 V;
[Ag(NH₃)₂]⁺ + e⁻ → Ag(s) + 2NH₃ , E₃^° = 0.373 V
2.303RT / F = 0.0591.
