A voltaic cell consists of a Zn/Zn2+ half-cell and a Ni/Ni2+ half-cell at 25 âC. The initial concentrations of Ni2+ and Zn2+ are 1.30molLâ1 and 0.120 molLâ1, respectively.
Zn2+(aq)+2eââZn(s)Eâ=â0.76V
Ni2+(aq)+2eââNi(s)Eâ=â0.23V
What are the concentrations of Ni2+ and Zn2+ when the cell potential falls to 0.46 V?
