Which formula is used to calculate the amount of substance decomposed during electrolysis?

The formula used to calculate the amount of substance decomposed during electrolysis is derived from Faraday's laws of electrolysis. The relationship expressed in this formula shows how the quantity of electric charge (Q) relates to the number of moles of a substance (n) involved in the electrochemical reaction.

In the correct formula, n = Q / (F * z), n represents the number of moles of the substance decomposed, Q is the total electric charge transferred during electrolysis, F is Faraday's constant (approximately 96485 C/mol), which represents the charge of one mole of electrons, and z is the number of electrons transferred per mole of the substance during the electrochemical reaction. This formula indicates that the amount of substance (in moles) that undergoes electrolysis is directly proportional to the total charge passed through the system and inversely proportional to the product of Faraday's constant and the number of electrons involved in the reaction.

This relationship is fundamental in electrochemistry, as it allows us to quantify how much of a substance can be converted into products based on the charge that has flowed through the electrolyte. Understanding this allows for precise control and prediction in electrochemical processes, which is essential for applications like electropl
