The Edison accumulator is symbolized by:
Fe(s) FeO(s) |KOH(aq, a) ||Ni2O3(s) |NiO(s) [Ni(s)
Where half-stack reactions are:
NizO3(s) + H20(1) + 2e 2NIO9 + 20H',
FeOs) + H2O(1) + 2e → Fes) + 2OH',
$° = 0,45 V
0° = -0,90 V
a) What is the overall reaction of the stack?
b) What is the standard electrical potential of the battery,
E°?
