Some classmates and I have been working on designing primary cells in our electrochemistry class. Our hypothesis stated that metals with different degrees of nobility, and an electrolyte with a high concentration of ions would make the most effective cell. While the first statement was true, the latter only applied to primary cells where both electrodes were non-noble metals. When one was a noble metal and one was not, we found that an electrolyte without a high concentration of ions, such as acetic acid, worked a lot better. We cross-referenced our results with other classmates, and they noticed the same thing. Have we all made a mistake? Or is there a factor we are not aware of? Please help!
