Using the calculator again we calculate the nonstandard potential of the Cd reaction. Suppose we now have a concentration of Cd 2 of 0.005 M what is its potential? The calculator should return a standard potential of -0.4 V and a nonstandard potential of -0.47 V. Place this value in the box for the second half-reaction then click on "Evaluate".

Sodium metal that forms at the hode floats up through the molten sodium chloride into a sodium-collecting ring from which it is periodically drained. The diaphragm that separates the two electrodes is a screen of iron gauze which prevents the explosive reaction that would occur if the products of the electrolysis reaction came in contact.

Palladium Pd refining can be a daunting task similar to the other Platinum group metals PGM's refining process. This is mainly due to their similar but different physical and chemical properties. Separating Palladium from base metals and especially from sister PGM's is rarely achieved completely in one refining cycle. Sounds kind of rough but rest assured that this process is doable
