b. (1) In an experiment a platinum electrode is immersed in a neutral solution of 0.10 mol dm Co?" and 0.04 mol dm. Zn* at 298 K. Identify the sequence of reduction reactions that will occur as the potential applied to the platinum electrode is varied from an initial value of 0.10 V to -0.80 V. [10 marks) E CoCo - -0.28 V E ZnZn = -0.76 V EHH2(g) = 0.00 V R-8.3145 J K mol! F-96485 C mol' (ii) Calculate the applied potential range required to separate the Co and Zn? 15 marks/ Page 1 of 2
