In order for a cell potential to be a standard cell potential, the concentration of all ions in solution must be 1.0 M, the partial pressures of all gaseous species must be 1.0 atm, and the temperature must be 298 K.
To determine the values for the blanks, we need to understand the concept of standard conditions. Standard conditions refer to a set of specific conditions that allow for standardized comparison between different electrochemical reactions.
For the concentration of ions in solution, it is standardized to 1.0 M. This means that the concentrations of all ions involved in the electrochemical reaction should be exactly 1.0 M. This ensures that the cell potential can be compared accurately with other cell potentials under the same standardized conditions.
For the partial pressures of gaseous species, it is also standardized to 1.0 atm. This means that the pressures of all gaseous species involved in the electrochemical reaction should be exactly 1.0 atm. This allows for accurate comparison of the cell potential with other reactions involving gaseous species.
Lastly, the temperature for standard cell potentials is standardized to 298 K (or 25 degrees Celsius). This specific temperature is chosen as it is a common and convenient reference temperature for electrochemical calculations. It allows for consistent and comparable values of standard cell potentials.
It is important to note that these standard conditions are used for comparison purposes and in theoretical calculations. In practice, actual cell potentials may deviate from the standard values due to factors such as non-ideal behavior of solutions or variations in temperature and pressure.
