investigation of electrolysis
... The experiment carried out aimed to monitor the quantity of Copper (Cu) metal deposited during the electrolysis of Copper Sulphate solution (CuSo4) using Copper electrodes, when certain variables were changed. ... Faraday’s First Law of electrolysis states that: “The mass of any element deposited during electrolysis is directly proportional to the number of coulombs of electricity passed” Faraday’s Second Law of electrolysis states that: “The mass of an element deposited by one Faraday of electricity is equal to the atomic mass in grams of the element divided by the number of electrons required to discharge one ion of the element. ... The actual results produce an almost straight-line graph, showing that: Mass of Copper a Time current Flows Therefore, it has now been proved, through this experiment, that both of Faraday’s Laws Of Electrolysis are correct. Faraday’s First Law of electrolysis states that: “The mass of any element deposited during electrolysis is directly proportional to the number of coulombs of electricity passed” Faraday’s Second Law of electrolysis states that: “The mass of an element deposited by one Faraday of electricity is equal to the atomic mass in grams of the element divided by the number of electrons required to discharge one ion of the element. ... Another factor which may have affected the overall outcome of the investigation, may have been the fact that the practical work of the investigation was carried over from lesson to lesson, meaning that variables such as the concentration or the amount of the Copper Sulphate solution could have changed between lessons.
