Igcse Model Questions Vol1 2022 Chemistry Question 16
Practice objective / multiple choice question 16 from the 2022 Igcse Model Questions Vol1 Chemistry examination.
A galvanic cell is constructed with a zinc electrode immersed in a \(0.010\ \text{M}\) Zn²⁺ solution and a copper electrode immersed in an unknown concentration of Cu²⁺ solution. The standard reduction potentials are \(E^{\circ}(\text{Cu}^{2+}/\text{Cu})=+0.34\ \text{V}\) and \(E^{\circ}(\text{Zn}^{2+}/\text{Zn})=-0.76\ \text{V}\). At \(25\ ^{\circ}\text{C}\) the cell emf is measured as \(1.05\ \text{V}\). Calculate the concentration of Cu²⁺ in the solution (express your answer in scientific notation to two significant figures).
