Question

Write the half-reactions as they occur at each electrode and the net cell reaction for this electrochemical cell containing tin and silver: sn(s)|sn2 (aq)||ag (aq)|ag(s)

Answer 1

  The  half  reactions    as  they  occur   at  each  electrode

is  as  follows

at  the  anode  Sn(s)  =sn^2+(aq)  +  2e  -
at  the  cathode  2  ag^+(aq)   + 2e -  =  2Ag (s)

net  cell  reaction  =   Sn (s)  +  2Ag^+(aq)  =  sn^2+ (aq) +  2  Ag  (s)
