Waec Model Questions Vol1 2019 Chemistry Question 42
Practice objective / multiple choice question 42 from the 2019 Waec Model Questions Vol1 Chemistry examination.
A galvanic cell is constructed as follows: Zn(s) | Zn^{2+} (0.010 M) || Cu^{2+} (0.10 M) | Cu(s). Standard electrode potentials are E°(Zn^{2+}/Zn) = -0.76 V and E°(Cu^{2+}/Cu) = +0.34 V. At 25 °C, the cell EMF is measured to be 0.9 V. What concentration of Cu^{2+} (in mol L⁻¹) would give this EMF?
