I recently carried out a laboratory experiment for my general chemistry 2 lab to experimentally determine the faraday constant. It involved the redox reaction Cu(s) + 2H+(aq)-->Cu2+ + H2(g). We used an electrolytic cell and collected H2 gas in a buret. Then, we proceeded to calculate the partial pressure of H2 gas, the ideal gas law to calcualte moles of H2 gas, then e- transferred and so on. I am currently trying to determine at least two possible sources of error for this experiment and how they would affect the determined faraday constant? (i.e. would it be higher or lower). Thank you in advance for any assistance or direction you can give.
