In my experiment, I basically looked at the effect of temperature of a voltaic cell and its effect on the Gibbs free energy (function) of the cell
I had a zinc sulfate
and copper sulfate
half cell, placed in a water-bath, and the Ecell values were measured through a multimeter Now the concentration of zinc sulfate was 0.01M while the concentration of copper sulfate was 1 M, and obviously I have to justify this difference in concentration
Truth is, when I connected the cells at 1M each, the voltage it displayed was too far off the 1.10V its supposed to be at
And I was confused why this could be happening. Then I did some trial and error and found that decreasing the concentration of zinc actually helps the value become closer to the real +1.10V for a zinc and copper galvanic cell
But now I have to explain why I did this. I cannot simply state that I have done trials and error and simply determined which concentration works. Is there ANY
possible explanation for it.
Thanks for the help.
