Waec Model Questions Vol1 2022 Chemistry Question 4
Practice objective / multiple choice question 4 from the 2022 Waec Model Questions Vol1 Chemistry examination.
Metal A forms a soluble nitrate. Its solid is placed in a solution that contains 0.010 M of metal B³⁺ ions (E°(B³⁺/B) = -0.45 V). The solubility product of A(OH)₃ is 1.0×10⁻³³ and the solution pH is 7.0. A cell is set up with A as the cathode and B as the anode, and a potential of +0.30 V is measured at 25 °C. Assuming unit activities, calculate the standard reduction potential E°(A³⁺/A).
