What is the standard reduction potential…?
Interesting. I’ve seen this same question on Yahoo, but with slightly different concentrations and cell potential. It sounds like several of you have been getting different questions from WebAssign or something similar. The problem with this problem is that if Y is indeed yttrium, there is no way that this reaction will actually produce a cell potential of 0.95 V. It may be that Y is simply an unknown like X. Here is the response that I gave to Elizabeth. Perhaps it can help you. In her version E was 1.10V, and Y3+ was 1.4M and Br- was 0.51M. Other than that, it was the same as yours. ====================================== Perhaps I am missing something, but I don’t see how this cell is producing a potential of 1.10 V. First we need to establish that the Y is indeed yttrium. And if so, yttrium has a reduction potential of -2.37 volts. Bromine has a reduction potential of +1.07 volts. Your line notation indicates that Y is being oxidized and bromine is reduced. Therefore the standard ce
