When solid copper is placed in an aqueous silver nitrate solution, a reaction occurs, as represented by the equation below.

Cu(s) + 2AgNO3(aq) --> 2Ag(s) + Cu(NO3)2(aq)

 

61 State the change in oxidation state for the copper in this reaction.

Answer-->  0 to +2

62 Based on Table J, state why Cu(s) reacts spontaneously with Ag+(aq).

Answer--> Cu is higher on table J than Ag

63 Write the balanced half-reaction to represent the reduction of the silver ions to silver atoms.

Answer--> e- +    Ag+  --> Ag

or 2e- +    2Ag+  --> 2Ag
