Electrochemistry
At 298 K the emf of the cell, standard hydrogen electrode ççsecond
half-cell constructed by taking standard hydrogen electrode as anode
(reference half-cell) and the other half-cell  as cathode, gives the reduction
potential of the other half-cell If the concentrations of the oxidised and
the reduced forms of the species in the right hand half-cell are unity,
then the cell potential is equal to standard electrode potential, Eo
R of
the given half-cell
