Neco 2017 Chemistry Question 21
Practice objective / multiple choice question 21 from the 2017 Neco Chemistry examination.
In a galvanic cell the half‑cells are Zn(s) | Zn^{2+} (0.010 M) || Cu^{2+} (x M) | Cu(s). The standard reduction potentials are (E^{\circ}(\text{Zn}^{2+}/\text{Zn}) = -0.76\,\text{V}\) and (E^{\circ}(\text{Cu}^{2+}/\text{Cu}) = +0.34\,\text{V}\). At (25^{\circ}\text{C}\) the cell emf is measured as 1.05 V. Calculate the concentration x of Cu^{2+} in the cell.
