What is the standard cell potential?
A cell's standard state potential is the potential of the cell under standard state conditions, which is approximated with concentrations of 1 mole per liter (1 M) and pressures of 1 atmosphere at 25oC.What is standard cell potential summary?
The standard cell potential is the potential difference between the cathode and anode. For more information view Cell Potentials. The standard potentials are all measured at 298 K, 1 atm, and with 1 M solutions.What is the formula for the standard cell potential?
The overall cell potential can be calculated by using the equation E0cell=E0red?E0oxid.- Electromotive Force (EMF) has been measured to be 1.100 V. A concentration of 1 M in an ideal solution is defined as the standard condition, and 1.100 V is thus the standard electromotive force, DEo, or standard cell potential for the Zn?Cu galvanic cell.
