A voltaic cell consists of a Zn/Zn2+ half-cell and a Ni/Ni2+ half-cell at 25 . The initial concentrations of Ni2 and Zn2 are 1.80 and 0.130 , respectively.
initial cell potential = .56
the cell potential when the concentration of Ni2+ has fallen to 0.500 = .52
The next question is ?
What is the concentrations of Ni2+ when the cell potential falls to 0.45 ?
and What is the concentration ofZn2+ when the cell potential falls to 0.45 ?
