Tollen's reagent is used for the detection of aldehyde. When a solution of AgNO_(3) is added to glucose with NH_(4)OH, then gluconic acid is formed. Ag^(+)toe^(-)toAg,E_(red)^(@)=0.8V C_(6)H_(12)O_(6)+H_(2)OtoC_(6)H_(12)O_(7) (Gluconic acid) +2H^(+)+2e^(-),E_(oxd)^(@)=-0.05V Ag(NH_(3))_(2)^(+)+e^(-)toAg(s)+2NH_(3),E^(@)=-0.337V [Use 2.303xx(RT)/(F)=0.0592 and (F)/(RT)=38.92 at 298K] Now answer the following three questions: Q. 2Ag^(+)+C_(6)H_(12)O_(6)+H_(2)Oto2Ag(s)+C_(6)H_(12)O_(7)+2H^(+) Find in K of this reaction: |
