The Faraday constant F is a fundamental physical constant that represents the charge of one mole of electrons. It is named after the scientist Michael Faraday and is used in electrochemistry to relate the amount of charge transferred during an electrochemical reaction to the amount of substance involved in the reaction. The Faraday constant is approximately equal to 96,485.34 Coulombs per mole of electrons C/mol .To calculate the Faraday constant using electrochemical data, follow these steps:1. Set up an electrochemical cell: An electrochemical cell consists of two electrodes anode and cathode immersed in an electrolyte solution. Connect the electrodes to a power source to drive the electrochemical reaction.2. Measure the current: Record the current I flowing through the cell in Amperes A .3. Measure the time: Record the time t for which the current flows through the cell in seconds s .4. Determine the amount of substance: Measure the amount of substance n that has been deposited or dissolved at the electrode during the electrochemical reaction. This can be done by weighing the electrode before and after the reaction and using the molar mass M of the substance to calculate the number of moles.5. Calculate the total charge transferred: Multiply the current I by the time t to obtain the total charge Q transferred during the electrochemical reaction in Coulombs C . Q = I t6. Calculate the charge per mole of electrons: Divide the total charge Q by the amount of substance n to obtain the charge per mole of electrons. F = Q / n7. Compare the calculated value to the known value of the Faraday constant: The calculated value should be close to the known value of the Faraday constant approximately 96,485.34 C/mol . Small discrepancies may be due to experimental errors or inaccuracies in the measurements.Example:Suppose you have an electrochemical cell where a current of 0.5 A flows for 3600 seconds 1 hour , and during this time, 2.5 grams of a substance with a molar mass of 50 g/mol are deposited at the electrode.1. Current I = 0.5 A2. Time t = 3600 s3. Amount of substance n = 2.5 g / 50 g/mol = 0.05 mol4. Total charge Q = I t = 0.5 A 3600 s = 1800 C5. Faraday constant F = Q / n = 1800 C / 0.05 mol = 36,000 C/molIn this example, the calculated value of the Faraday constant is 36,000 C/mol, which is significantly lower than the known value of 96,485.34 C/mol. This discrepancy may be due to experimental errors or inaccuracies in the measurements. To improve the accuracy of the calculation, ensure that the measurements are precise and repeat the experiment multiple times to obtain an average value.
