Igcse Model Questions Vol1 2021 Chemistry Question 15
Practice objective / multiple choice question 15 from the 2021 Igcse Model Questions Vol1 Chemistry examination.
A concentration cell is set up with two copper electrodes. The left half‑cell contains a 0.010 mol dm⁻³ CuSO₄ solution and the right half‑cell contains a 0.10 mol dm⁻³ CuSO₄ solution, both at 25 °C. (i) Calculate the electromotive force (EMF) of the cell. (ii) The cell is connected across a 10 Ω resistor and allowed to run for 2.00 h. Assuming 100 % current efficiency, calculate the mass of copper deposited on the cathode. (Use \(F=96 500\) C mol⁻¹ and \(M_{\text{Cu}}=63.55\) g mol⁻¹.)
