As quickly as possible. I have a science experiment and my results came out kind of jumpy, they support my hypothesis, but at certain points there are unusual shifts, my opinion being the seemingly fault measuring devices. Any comments as to the truth behind my hypothesis would be helpful. All of these are in reguard to a daniel cell made of a half cell of ZnSO4 (aq) and a half cell of CuSO4(aq), with corresponding metal electrodes linked by a salt bridge of saturated NH4NO3(aq) under normal temperature and pressure, with 1M solutions. 1) The rise in temperature will yield a rise in current and slight rise in voltage. 2) As the solutions become more concentrated(.01M, .1M, .5M, 1M, 2M) there will be a proportional rise in current and moderate rise in voltage. 3)As the electrodes surface area grow there will be a proportional rise in current and no rise in voltage. Thanks. Bob.
