A nickel electrowinning cell consists of 36 anodes and 35 bagged cathodes 11m2 cross-sectional area) into which electrolyte at a concentration of 58.7g/L nickel (atomic mass 58.7) at a pH of 4 is fed at a flow rate of 1.5m3/h. This flow is distributed equally into each cathode bag. The cell operates with a current density of 400A/m2 with a cathodic current efficiency of 95%. (Note that the rate of removal, v, of nickel from the feed electrolyte in one compartment of the cell is given by v=MitF; where F=96,485C/ mole- e). a) Give balanced equations for the main cathodic and anodic reactions in the cell. Calculate the concentrations of the nickel and acid in the solution leaving the cell, assuming that the cell can be treated as a perfectly mixed reactor. [7 marks] c) Calculate the pH of the catholyte, assuming no diffusion of protons from the anolyte. [5 marks] f) What would happen if no diffusion from anolyte to catholyte were to occur
