The cell is capable of measuring a compensating potential difference (cpd) to =0.1 mV or better, a precision comparable with that obtainable with well-behaved galvanic cells. The cpd's of the cells: 1. Hg(N 2)| |HCl(aq, m)|Pt, H 2 2. Hg(N 2)| |HCl(aq, m)|AgCl|Ag have ...
(1),ΔE1/2 is the difference between the standard potential of the cell and the potential of the reduction–oxidation couple, R is the ideal gas constant, T is the temperature in Kelvin, F is Faraday's constant, and KΙΙ and KΙΙΙ are the equilibrium constants of EuII and EuIII...
Explain the difference between a strong and weak electrolyte. Give an example of each. Why are electrodes, salt bridges, and electrolytes important to the operation of a galvanic cell? Describe what is meant by the term standard electrode potential. ...
Moreover, another significant difference between electrode potential and cell potential is that it is impossible to measure the electrode potential because it is a relative value, but cell potential can easily be measured because we need to find the difference in electrode potentials, which are relat...
