Hossein Rabiei-Samani Chemistry 1552 – Mon Thursday, April 22, 2010 Eftalda Becka, Manisha Kapoor Electrolysis: Faraday’s Law and Determination of Avogadro’s Number Introduction Electrolysis is a chemical decomposition reaction produced by passing an electric current through a solution containing ions. In this experiment, the process of electrolysis was used in order to determine how many atoms of hydrogen are present in one mole of the gas. To be able to accomplish this, the pressure of the dry hydrogen gas first must be measured in the solution. Then by using the ideal gas law, the moles of the atoms in the gas could be found. Finally by using Faraday’s law, the amount of the hydrogen in one mole of the gas could be verified. Faraday’s law is the amount of any substance that gets dissolved in the process of electrolysis and it is proportional to the total electric charge passed. Objective
