Question

what is the potential range of separation of Cobalt​

Answer 1

Answer:

Cobalt dissolution is observed in alkaline solutions at potentials as negative as −850 mV vs. Hg|HgO [20, 22, 23, 33–37] and depends on pH [20]. It is not clear, however, whether the dissolution is a step in the overall process of Co(II) layer formation or a side reaction only [22, 25, 33].
