I had to make a galvanic cell for my chemistry class and it was supposed to have a voltage of 2.3 but for some reason it only was .5. My cell was comprised of a iron and aluminim electrode with the respective nitrates.( potassium nitrate salt bridge) it was wondering if anybody knew why it would have such a low voltage. I sanded the electrodes to expose fresh umoxidesed metal.
