A Concentration Cell Is Made Using Ni²⁺ solutions and Ni

question 12

Essay

A concentration cell is made using Ni²⁺ solutions and Ni electrodes.In one compartment, [Ni²⁺] = 1.00 M; in the other, [Ni²⁺] is due to the dissolution of Ni(OH)₂ in an aqueous solution buffered to a pH of 13.000.The measured E_cell at 298 K is 0.4038 V.Find the concentration of Ni²⁺ in the saturated Ni(OH)₂ solution, and calculate an estimate of K_sp for nickel hydroxide.
