Passage IV Tollen s reagent is used for the detection of aldehydes When a solution of AgNO is added to glucose with NH OH then gluconic acid is formed Ag eAg Ered 0 80 V C6H12O6 H O C6H 2O 2H 2e Gluconic acid Ag NH3 e Ag s 2NH3 RT Use 2 303 x 0 0592 and F RT Ex 0 05 V Ered 0 337 V 38 92 at 298 K 2006 3 x 4M 12M 32 2Ag C6H 2O6 H O2Ag s C6H 2O7 2H Find In K of this reaction a 66 13 0 58 38 c 28 30 d 46 29 33 When ammonia is added to the solution pH is raised to 11 Which half cell reaction is affected by pH and by how much a Foxi will increase by a factor of 0 65 from E b Exi will decrease by a factor of 0 65 from E c Ered will increase by a factor of 0 65 from E d Ered will decrease by a factor of 0 65 from Ered oxi oxi 34 Ammonia is always added in this reaction Which of the following must be incorrect a NH combines with Ag to form a complex Ag NH3 is a stronger oxidising reagent than Ag c In the absence of NH3 silver salt of gluconic acid is formed d NH has affected the standard reduction potential of glucose gluconic acid electrode
