Avoltaic electrochemical cell consists of a copper electrode in a cu2so4(aq) solution, and a palladium electrode in a pdso4(aq) solution at 25°c. the salt bridge consists of a solution of kcl(aq).
what is the concentration of the cu+if the concentration of the pdso4 is 0.498 m and the measured cell potential is 0.447 v?
given: cu+(aq) + e- ↔ cu(s) e°=+0.521 v
and pd2+(aq) + 2e- ↔ pd(s) e°=+0.987 v

![\begin{array}{rcl}Q & = & \dfrac{\text{[Cu$^{+}$]}^{2}}{\text{[Pd]}}\\\\4.392 & = & \dfrac{{x}^{2}}{0.498}\\\\x^{2}& = & 2.187\\x & = & 1.48\\\end{array}\\\text{The concentration of Cu$^{+}$ is $\large \boxed{\textbf{1.48 mol/L}}$}](/tpl/images/0269/7404/9da92.png)
