Show that their for two half reactions having potentials E_1 and E_2 which are combined to give a third half reactions having potential E_3 is E_3=(n_1E_1+n_2E_2)/n_3
STATEMENT-1: We cannot add the electrode potential in order to get electrode potential of third electrode if no. of moles of electrons exchanged are not same. STATEMENT-2: Electrode potential is an extensive property
Standard electrode potential is the electrode potential when the concentration of all line species involves in a half cell?
The differences between the electrode potentials of two electrodes when no current is drawn through the cell is called……….
Two cells of e.m.f E_1 and E_2 have internal resistance r_1 and r_2 respectively. What is the corresponding formula for the series combination?
n cells, each having emf e, are connected in series what is the emf of the combination?
Electrode potential of the half Pt(s)|Hg(l)| Hg_(2)Cl_(2)(s) | Cl^(-)(aq) can be incresed by :
If cell potential of standard cell is 0.59 V then equilibrium constant for the cell reaction occurring in the cell at 25^(@)C is (n = 1)
If the half-cell reaction A+e^(-)toA^(-) has a large negative reduction potentials, it follows that:
n cells, each of emf E are connected in parallel. The effective emf of the parallel combination is:
