At the more concentrated electrode, the concentration of the ions in solution needs to be decreased. The electrons move through the wire generating a voltage and end up at the more concentrated electrode. In the less concentrated cell, the electrode would break down to increase the concentration of ions in solution by oxidation. This difference in concentration is enough for a voltage to be generated. RT and F can also be simplified if at 298K to 0.0257 to make the equation simpler.Ī concentration cell is a voltaic cell that has the same electrodes but different concentrations of electrolytes on either side of the cell joined by a salt bridge. Q can be calculated by resolving the logarithm of the concentrations of the oxidized and reduced cell. The standard cell potential can be calculated using reference values at standard temperatures and conditions.
NERNST EQUATION CALCULATOR FULL
It can also be used to determine the total voltage, or electromotive force, for a full electrochemical cell. The Nernst equation can be used, in conjunction with other information, to determine the reduction potential of a half-cell in an electrochemical cell. In electrochemistry, the Nernst equation relates the reduction potential of an electrochemical reaction to the standard electrode potential, temperature, and activities of the chemical species undergoing reduction and oxidation.
