Neco 2023 Chemistry Question 3
Practice objective / multiple choice question 3 from the 2023 Neco Chemistry examination.
A galvanic cell is constructed as Zn(s)\,|\,Zn^{2+}(0.010\,\text{M})\,||\,Cu^{2+}(x\,\text{M})\,|\,Cu(s) at 25°C. The measured cell EMF is 1.05 V. Given standard reduction potentials E^{\circ}(Zn^{2+}/Zn) = -0.76 V and E^{\circ}(Cu^{2+}/Cu) = +0.34 V, calculate the concentration x of Cu^{2+} in the right half‑cell.
