Question

In a galvanic cell a spontaneous redox reaction occurs However, the reactants are separated such that the transfer of electrons is forced to occur across a The resulting electricity is measured in volts(V) and is the sum of the potentials of the oxidation and reduction half-reactions: By reversing the reduction half-reactions you get the corresponding oxidation sign of You can also write the equivalent equation in terms of the reduction potentials and avoid manipulating standard potentials A table of standard reduction potentials gives E and values for common half-reactions. Calculate the standard potentials for the following galvanic cell which has the overall balanced equation In the context of the zinc-silver cell described in Part A, match each of the following descriptions to the anode or cathode

Explanation / Answer

Part A :

Lets write the half reactions on anode and cathode

Reaction on anode :
